Number the five seats from left to right because everyone faces North. Place Kabir at seat 1 from the extreme-left clue. Om is second to the right of Kabir, so Om must occupy seat 3. Mohan is immediately left of Om, fixing Mohan at seat 2. Place Naina at extreme-right seat 5; consequently Leela, immediately left of Naina, occupies seat 4. The completed arrangement is Seat 1: Kabir | Seat 2: Mohan | Seat 3: Om | Seat 4: Leela | Seat 5: Naina. The question asks: Who sits at the extreme right? Kabir is incorrect because Kabir occupies seat 1, which does not satisfy the requested position. Mohan is incorrect because Mohan occupies seat 2, which does not satisfy the requested position.
