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: How many people sit between Kabir and Leela? 1 is wrong because more than one seat lies between them. 3 is wrong because only seats 2 and 3 are strictly between seats 1 and 4. Every original clue is satisfied simultaneously, and no seat remains ambiguous.
