The answer you are looking for actually is
C. The atmosphere is composed of heavier molecules at lower atmospheric levels. I know this because someone answered it before and it is verified. :) but it is wrong on some tests. you learn something new everyday.

Answer:

Option D

Explanation:

When the wind is moving near to the earth surface , its speed reduces due to the presence of surface objects such as mountains, trees, houses, poles, and all other man made objects.

how ever,  when the wind is moving at a higher altitude (much above the surface obstructions) , the disturbance get reduced  thereby reducing the friction and hence  the speed of the wind increase at higher altitude.

Thus, option D is correct
