Answer:

B. The pressure reading increases.

Explanation:

Gas pressure is an absolute pressure and atmospheric pressure decreases as height with respect to sea level is increased. Gauge pressure is the difference between absolute pressure and atmospheric pressure. Therefore, absolute pressure remains the same and gauge pressure reading increases.

The correct answer is option B.
