On increasing number density for a gas in a vessel, mean free path of a gas

Statement I: Mean free path of gas molecules,varies inversely with density of the gas Statement II: Mean free path of gas molecule is defined as the average distance travelled by a molecule between two successive collisions.

Mean free path of a gas molecule is

What do you mean by mean free path of a gas molecule?

(A): Mean free path of gas molecules, varies inversely as density of the gas. (R): Mean free path of gas molecules is defined as the average distance travelled by a molecule between two successive collisions.

If the temperature and pressure of a gas is doubled the mean free path of the gas molecules
