With respect to the given assertion and reason. Choose the correct option.
Assertion [A]: With an increase in the temperature of a gas inside a container, its pressure also increases.
Reason [R]: Upon heating, the kinetic energy of the gas molecules increases, which in turn results in a greater force exerted on the walls of the container.
