The correct answer is **a. The air is thinner**.
As you ascend to higher altitudes, the air pressure decreases, which means there are fewer oxygen molecules in the same volume of air (thinner air). This results in less oxygen being available for breathing, making it harder to breathe. While option b is incorrect because the air pressure decreases at high altitudes, options c and d are also not accurate in the context of high mountain breathing difficulties.
