The correct option is C. The aptitude tests that are given to job applicants during interview are designed to test the ability of the job applicants to think and to solve problems. The tests usually assess the applicants' thinking performance and their ability to handle the tasks that are related to the positions they are seeking for.
PS. What helps me remember is that in the movie Divergent they all had to take an aptitude test in which they performed problems in the best of their ability.
