Explanation
As per syllabus page 35:
3.2.4. Review Types
There exist many review types ranging from informal reviews to formal reviews. The required level of formality depends on factors such as the SDLC being followed, the maturity of the development process, the criticality and complexity of the work product being reviewed, legal or regulatory requirements, and the need for an audit trail. The same work product can be reviewed with different review types, e.g., first an informal one and later a more formal one.
Selecting the right review type is key to achieving the required review objectives. The selection is not only based on the objectives, but also on factors such as the project needs, available resources, work product type and risks, business domain, and company culture.
Some commonly used review types are:
• Informal review. Informal reviews do not follow a defined process and do not require a formal documented output. The main objective is detecting anomalies.
• Walkthrough. A walkthrough, which is led by the author, can serve many objectives, such as evaluating quality and building confidence in the work product, educating reviewers, gaining consensus, generating new ideas, motivating and enabling authors to improve and detecting anomalies. Reviewers might perform an individual review before the walkthrough, but this is not required.
• Technical Review. A technical review is performed by technically qualified reviewers and led by a moderator. The objectives of a technical review are to gain consensus and make decisions regarding a technical problem, but also to detect anomalies, evaluate quality and build confidence in the work product, generate new ideas, and to motivate and enable authors to improve.
• Inspection. As inspections are the most formal type of review, they follow the complete generic process. The main objective is to find the maximum number of anomalies. Other objectives are to evaluate quality, build confidence in the work product, and to motivate and enable authors to improve. Metrics are collected and used to improve the SDLC, including the inspection process. In inspections, the author cannot act as the review leader or scribe.
A.
1C (Technical Review is performed by technically qualified reviewers and led by a moderator): This matches the description of a Technical Review.
2D (Walkthrough is led by the author, and it can serve many objectives, such as evaluating quality and building confidence in the work product): This is an accurate description of a Walkthrough.
3A (Inspection is the most formal type of review. Its main objective is to find the maximum number of anomalies): This correctly describes an Inspection.
4B (Informal review does not follow a defined process and its main objective is detecting anomalies): This matches the description of an Informal Review.
B.
1D (Technical Review is led by the author and serves many objectives): Incorrect because a Technical Review is not led by the author but by a moderator.
2C (Walkthrough is performed by technically qualified reviewers and led by a moderator): Incorrect because a Walkthrough is led by the author, not a moderator.
3A (Inspection is the most formal type of review. Its main objective is to find the maximum number of anomalies): Correct.
4B (Informal review does not follow a defined process and its main objective is detecting anomalies): Correct.

2D (Walkthrough is led by the author, and it can serve many objectives): Correct.
3C (Inspection is performed by technically qualified reviewers and led by a moderator): Incorrect because it describes the Technical Review not Inspection
4B (Informal review does not follow a defined process and its main objective is detecting anomalies): Correct.
D.
1B (Technical Review does not follow a defined process): Incorrect because this is an accurate description of an informal review not a Technical Review.
2D (Walkthrough is led by the author and serves many objectives): Correct.
3C (Inspection is performed by technically qualified reviewers and led by a moderator): Incorrect because this is an accurate description of a Technical Review not an Inspection.
