About this MCQ
This Medium Analytical Reasoning MCQ checks one syllabus fact.
The question is: “Which of the following does not belong with the others: Copper, Iron, Aluminum, Oxygen?”
The accepted answer is A. Oxygen. Oxygen is the person, body, or term that satisfies “Which of the following does not belong with the others: Copper, Iron, Aluminum, Oxygen” (option A). Option B (“Aluminum”) does not match the stem; it is a near-miss used to catch incomplete recall of Oxygen. Option C (“Copper”) does not match the stem; it is a near-miss used to catch incomplete recall of Oxygen. Remaining alternatives (Iron) fall outside the same rule and should be eliminated once Oxygen is identified. Analytical Reasoning questions of this type reward precise definitions rather than approximate associations. Analytical Reasoning recall of this distinction is a regular item in FPSC, PPSC, NTS, and CSS papers.
