Answer:
B. Increasing temperature.
Explanation:
Atmospheric pressure increases with increasing temperature because warm air causes the atmospheric pressure to rise.
Basically, when the molecules contained in air experience a collision, they usually exert forces on one other, and when these molecules become heated, they experience a quick and rapid motion leading to an increased rate of collision. Therefore, as more force is being exerted on the air molecules, the atmospheric pressure tends to rise or increase.
