The UPSC Civil Services Prelims 2026 CSAT Paper-II (Set A, English) answer key. All 80 questions, derived by matching each Set A question against our Set D detailed solutions — content is identical across sets, so the correct answers are the same; only the option letters (a/b/c/d) differ because UPSC shuffles option order per set.
Note. How UPSC sets work. All four sets (A, B, C, D) of the same paper test the same 80 questions — but UPSC reorders the question sequence and shuffles the option labels within each question to discourage copying. Set A Q5 may be Set D Q65, with different (a)(b)(c)(d) labelling. Our cross-reference table below maps each Set A position to its Set D counterpart so you can click through to the full reasoning.
