Answer: Option (A) is the correct answer.
Explanation:
It is known that particles of a gas are held by weak Vander waal forces, therefore, there is no force of attraction between gas molecules.
As a result, these particles are in random motion.
Thus, we can conclude that out of the given options, the constant motion of the particles in a gas allows a gas to fill a container.
