Answer: Option (D) is the correct answer.
Step-by-step explanation:
It is known that relation between pressure and force is that, pressure equals force divided by area.
Mathematically, P =

where P = pressure
F = force
a = area
Hence, when there is increase in number of gas particles in a container the there will be more number of collisions due to increase in number of particles. This will lead to greater collision force and as a result there will be increase in pressure because force is directly proportional to pressure.
Thus, we can conclude that the sequence more collisions --> greater collision force --> higher pressure best describes the result of increasing the number of gas particles in a container best describes the result of increasing the number of gas particles in a container.
