Answer: Option (B) and (F)
Explanation:
Pressure and Density, both are inversely proportional to the height.
The air molecules are mostly present near the surface because of its higher density and the gravitational force that forces them to accumulate near the earth's surface. And as we go up, these air molecules gradually decreases in number and their density also becomes very less, as a result of which the pressure and density both subsequently reduces.
Thus, the correct options are mentioned above, i.e the pressure as well as density both decreases with the increasing height.
