Correct : c

Explanation:
1. Analyze the Compass: The map provides a standard direction key in the bottom-right corner where North (N) is Up, South (S) is Down, West (W) is Left, and East (E) is Right.

2. Evaluate Statement (a): The library is located directly West of the canteen, not northwest. (Incorrect)

3. Evaluate Statement (b): The hospital is located directly North (across 5th Cross Road) of the chemistry lab, not east. (Incorrect)

4. Evaluate Statement (c): Look at the positions relative to each other:
• The physics lab is in the northwest quadrant (top-left).
• The chemistry lab is in the southeast quadrant (bottom-right).
• Moving from the physics lab to the chemistry lab requires moving Down (South) and Right (East). Therefore, the chemistry lab is indeed to the southeast of the physics lab. (Correct)

5. Evaluate Statement (d): The classrooms are in the southwest corner and the canteen is in the northeast corner. They are diagonally opposite each other and not next to each other. (Incorrect)
