Air exerts pressure primarily because it has mass. This means that air is made up of molecules that occupy space and have weight. When these molecules collide with surfaces, they exert a force on those surfaces, leading to air pressure.

While temperature does play a role in the behavior of air and can affect pressure (for example, warmer air tends to be less dense and can rise, creating areas of lower pressure), the fundamental reason air exerts pressure is due to the presence of mass and the kinetic energy of air molecules. So, the correct answer to why air exerts pressure is "because air has mass."
