Data Sufficiency — Circular Seating & Facing (All Facing Centre?) Are A, B, C, D, and E — around a circle — all facing the centre? I. B sits second to the right of D. D faces the centre. C sits on the immediate right of both B and D. II. A sits on.

Question

Solve this multiple-choice question and choose the correct option.

Accepted Answer

Introduction / Context:We must decide common facing from relational seating facts. With three statements, we adapt options to pair/triple sufficiency. Given Data / Assumptions: I provides D’s facing and a right-of chain but leaves ambiguity for A. II provides adjacency of A/B and the right-of relation C/D. III provides tight neighbourhoods linking D, A, C, B in a cycle. Concept / Approach:Combining II and III yields a forced cycle consistent only when everyone faces the centre; attempts to flip facing create contradictions in “immediate left/right”. Step-by-Step Solution: 1) From III, fix the triangle (A,B,C) around D.2) Apply II to position A left of B and C right of D, collapsing orientation.3) Check alternatives under outward facing — contradictions arise. Final Answer:II + III suffice.
