D Correct answer
Explanation

When people are positioned on or climbing a mountain, we use the preposition 'on'. 'On the mountain' indicates they are physically located on its surface or slopes. 'In' would suggest being inside something, 'for' indicates purpose, and 'off' suggests removal or separation - none of which describe climbers' position on a mountain.
