Who is sitting third to the right of O?

Concept: In a double-row seating arrangement, two rows of people can face the same direction or opposite directions. Whenever a question asks for a seat "to the right" of a named person, that direction is read using the compass given with the diagram (north = up) combined with which way that person's row is facing — not automatically the reader's own left-right sense.

Application

1. The arrows in the diagram show that the bottom row (M, O, P, Q, N) faces north, since its arrows point upward toward N on the compass.

2. Because this row faces north, each person's right hand points east — the same direction as rightward movement across the diagram — so the row can be read straight across from left to right.

3. Reading the bottom row from left to right gives the order M, O, P, Q, N, with O in the second seat.

4. Stepping one seat to the right of O reaches P, a second step reaches Q, and a third step reaches N.

Cross-check: The top row (C, E, D, B, A) faces south instead, so if the same seat had to be located from that row's own perspective, left and right would swap — a reminder that the compass, not the page alone, decides direction. Reapplying the north-facing rule to the bottom row independently confirms the same seat, three places after O.
