Validity means...

Explanation:
Validity is about whether a test really measures what it is intended to measure. It focuses on accuracy—whether the instrument captures the true construct or outcome of interest. A test can be consistent (reliable) but still miss the intended construct, measuring something else instead. Feasibility aspects like cost, speed, or the number of participants concern practicality, not validity. So the best description is the accuracy or truthfulness of tests or instruments.
