As the altitude increases, the air density tens to decrease. Hence, option A is not correct.
The density of the air determined how many atoms of air can occur in a particular volume, In other words, it determines how tightly or loosely atoms of air are packed in a particular volume.
Hence, when the air density will increase, the molecules will be more tightly packed and the pressure will be more.
