Which statement correctly separates validation and verification?
A. They are two names for the same check.
B. Verification tests a range; validation tests double entry.
C. Validation tests whether data is reasonable; verification tests whether it was copied accurately.✓ 答案
D. Neither check can be used on a form.
解說
Range, type and presence checks are validation. Double entry and proofreading are verification. A value can pass both and still be the wrong fact if it was copied consistently from a wrong source.
