Correct answer: A
Explanation
Boundary Value Analysis (BVA) focuses on testing the boundaries of input ranges. For the valid age range of 18 to 99, the most appropriate test values are:
18: The lower boundary value.
19: Just above the lower boundary.
98: Just below the upper boundary.
99: The upper boundary value.
100: Just above the upper boundary.
