Six people (P–V) sit in a row facing north. Q is equidistant from R and S. P is second to the left of T. U is adjacent to V but not at any end. How many positions are possible?
Correct: A
Row arrangements require testing permutations respecting all constraints. Q's equidistance condition narrows R/S placement. P-T positioning splits possibilities. U-V adjacency creates only one stable configuration after all conditions are applied.
