B Correct answer
Explanation

On a sphere, longitude lines converge toward the poles. When you fly 500 km north from Delhi, you're at a different longitude. The east and west legs are along different latitude lines (different circumferences), but because of Earth's curvature and convergence, you end up slightly east of your starting point.
