  • The correct answer is D.
    It's a simple English comprehension.
    You should understand that in gases, intermolecular distances between gas molecules are large which means that they are farther away from one another with large spaces which makes the gas molecules to maintain a continuous random and oscillatory motion, colliding with themselves and the walls of their contained vessel and not negligible.However, cohesive forces amongst them is totally negligible because there's no cohesive force of attraction among gas molecules but a feeble Van dear Waals force of attraction.
