Answer is option C. The gas is placed under increased pressure.
Explanation:
According to Gas laws,
If the temperature to gas increases then the molecules of gas gets additional energy and moves with more spped than earlier which gives more more colliding to the walls of container. This increases pressure.
The volume and gas in a container are directly proportional to each other.
This means if the volume gets decreased then the collision of gas molecules to the walls increases which results increase in pressure.
Therefore, volume is inversely proportional to pressure.
