Concept:The key difference is between objective and projective personality tests.
Explanation:16-PF is a self-report questionnaire developed by Raymond Cattell. It measures personality through objective, structured questions.
T.A.T. (Thematic Apperception Test), Cloud Picture Test, and Draw-a-Man Test are all projective tests. They rely on interpreting ambiguous stimuli to uncover hidden thoughts.
Projective tests are subjective and open-ended. Objective tests, like 16-PF, have fixed response options and score objectively.
Since 16-PF is objective while the other three are projective, it is the odd one out.
Answer:Option B (16-PF) is the odd one out.
