Show answer & explanation
Correct answer: B
Solution: Step-by-step reasoning. From A wishing D good luck for Q, assign D = Q.
Given B appeared in R, assign B = R.
C is not in S or T, so C must be in one of P, Q, or R. But Q and R are already taken (by D and B), so C = P.
Therefore, C appeared for exam P.
