Reveal correct answer
Correct answer: D
A.
The "New image" option captures only the new version of the item after the modification, but does not retain the old state.
B.
The "Keys only" option captures only the primary keys of the modified items, which does not provide information about the content of the items before or after the modification.
C.
The "Old image" option captures only the state of the item before the modification, which is insufficient for auditing purposes where both the old and new states are required.
D.
The "New and old images" option captures both the old and new versions of items, which is useful for auditing changes, as it provides a complete before-and-after view of the data.
