How is air density related to air pressure

Now there are less molecules per unit of volume, so the density is lower. Now in aviation and meteorology when we talk about atmospheric pressure, that is slightly different, and is less related to atmospheric density. ... The outside pressure is constant, so the density actually decreases as temperature increases

im pretty sure its b

answer: i have one answer
