Solution

The correct option is A increase
We know the relationship between the average kinetic energy of a gas and its temperature is $K E_{a v g} = \frac{3}{2} K T$

When gas cylinder is kept on an accelerting van, this will increase speed of the gas molecules as inertial forces acts on it. Therefore, increasing average translational kinetic energy. Hence, temperature will increase.
