Difficulty: Medium
Correct Answer: Immediate right of C
Explanation:
Introduction / Context:
In circular seating with all facing inward, “right” means the counterclockwise neighbor and “left” means the clockwise neighbor. We must position five members to identify B’s exact neighbor relationship.
Given Data / Assumptions:
Concept / Approach:
Build a consistent clockwise sequence that contains both triples. Because D must be counterclockwise of E and clockwise of C, the segment (clockwise) C, D, E is fixed. Then attach the B–A piece so that A is adjacent to E.
Step-by-Step Solution:
Take clockwise order: C, D, E, A, B.This satisfies D right of E (counterclockwise) and D left of C (clockwise), and A between E and B.In this arrangement, the immediate right of C (counterclockwise neighbor) is B.
Verification / Alternative check:
Check alternatives and you will either break A-between-(B,E) or the D–E–C adjacency requirements.
Why Other Options Are Wrong:
They assign B adjacent to the wrong members or on the wrong side relative to A/E.
Common Pitfalls:
Using “classroom” right/left instead of inward-facing conventions (which invert sides).
Final Answer:
Immediate right of C
