C.  Personality tests

Explanation:

Personality test is a method of testing, examining or carrying out assessment of individuals personality ideas. It makes use of a self rating questionnaire, often considered to be subjective, due to the fact that, it is susceptible to response distortion which can be as a result of lack of self knowledge or insight of the individual.

Hence, it is considered to have a low validity because, there is high tendency that it may not actually measure what it sets out to measure, due to response distortion from the subject of the study.

Therefore, when compared to Structured interviews, cognitive ability test and job knowledge test, it has the lowest validity.
