A) Measures or predicts what it is supposed to measure or predict.

Explanation:

Validity allows us to measure if a test is good at measuring what it ´s supposed to measure. One of the greatest concerns in Psychological assessment is whether or not a test is actually measuring what we want. A test is valid when guarantees that the results are a true representation of the dimension under assessment. For example, a test aimed to measure a stable personality trait might actually be measuring transitory emotions caused by environmental conditions.
