Why does changing the volume of a container change the pressure of the gas in it?

A: Changing the volume reduces the number of molecules so they hit the walls of the container less often.

B: Changing the volume reduces the force with which the molecules hit the walls of the container.

C: Changing the volume increases the speed of the molecules so they hit the walls of the container more often.

D: Changing the volume increases the area that the molecules collide with so the force is spread over a larger area.

I think it's D but not sure
