Step-by-step explanation:
By definition, when a test or technique measures what it intends to, it is valid.
The answer is option A.

Reliability and validity are both approximately how nicely a technique measures something: Reliability refers to the consistency of a measure (whether or not the consequences can be reproduced below identical situations).
Validity refers back to the accuracy of a measure (whether or not the results really do constitute what they may be speculated to a degree).
