He will need to take the first route, Route A.  This is because if you look, the drops are far more spaced away from each other than that of b,c, or d.

Route A

Explanation:

From the topographical map, one can determine the steepness of the mountain. Close contours indicate a steep slope but wide contours depict a gentle and a broad slope. The wider the contours, the broader is the slope.

In the given image, the most favorable path will be route A as the contours are widely arranged, indicating a much gentle slope. The route might be long but is efficient. So the mountaineer will decide to take the route A to climb the mountain without much difficulty and risk factor.
