Ten people sit in two parallel rows (5 each), Row1 facing south, Row2 north. X is third to left of Y. Z is diagonally adjacent to W. M and N face opposite directions. Who is second to the right of O?
Correct: C
Parallel row arrangements require aligning row positions through directional clues. Diagonal adjacency between Z and W creates a fixed pair. Opposite-facing constraint reduces options for M/N positions. Tracing O's neighbors yields the correct second-right candidate.
