Mental ability is a type of personal qualification. Which option is an example of a personal qualification?

• A. Attendance at training
• B. Salary level
• C. Brand loyalty
• D. Mental ability

Answer: (D)

Personal qualifications are the attributes a person brings that influence their ability to perform tasks. Mental ability fits here because it reflects cognitive capacity—reasoning, memory, problem-solving, and the ability to learn—which directly affect how well someone can do work and adapt to new skills. The other options are not intrinsic qualifications: attending training is an activity used to develop skills, not a standing qualification; salary level is a compensation outcome, not a personal attribute; brand loyalty is a consumer attitude, not a work-related capability. So, mental ability uniquely exemplifies a personal qualification.
