Solution

The correct option is B
The pressure will increases

As mentioned in a question the container is rigid which means no gas particles are escaping from the container.
Now if we are heating the gas the pressure will increase because the average kinetic energy of the gas particles is increasing so the collision between the walls and gas particles will increase.
Density and volume will remain the same as no increment or decrement is taking place in no of the moles of a gas.
