The correct answer is "the amount of heat in each area." The pressure difference between the equator and the poles is primarily caused by the unequal distribution of heat across the Earth's surface. This is due to the differential heating of the Earth by the sun. The equator receives more direct sunlight and thus is warmer, while the poles receive less direct sunlight and remain colder.
The uneven heating of the Earth's surface causes air to rise at the equator, creating low pressure, and sink at the poles, creating high pressure. This pressure difference then drives the movement of air from areas of high pressure to areas of low pressure, creating wind patterns.
To get to this answer, you need to understand the basic concept of atmospheric pressure and its relationship to temperature.
