I think its B but I'm not sure about A... Please help

Temperature and volume vary directly, so if temperature decreases, so does volume. Volume decreases because the measure of the average kinetic energy of the gas particles (temperature) is decreasing also. When that happens, a gas cannot expand, and will decrease.

Yeah so then the molecules would move more slow. So isn't it B?

oFCOURSE. BECAUSE KINETIC ENERGY DECREASE MOLECULES MOVE SLOW
