Assuming that all other variables remain constant:

An increase in temperature will result in a higher atmospheric pressure -
a
higher temperature speeds up the movement of the air molecules, thereby
raising the pressure they exert on the surrounding atmosphere.

A) True
B) False

False and/or True.

The air can expand. If it expands vertically, the pressure is unchanged. If
it expands horizantally, the pressure goes down. If the air is constrained,
the pressure goes up.

Depends on what you mean by "all other variables remain constant"
