By charles law.
At constant pressure volume is directly proportional to temperature.
At constant pressure volume is directly proportional to temperature.

PV=RT
P=constant.
Therefore, when gas is cooled so temperature decreases so eventually volume will also decrease since direct relationship exists.
P=constant.

Yes @Manoj. But when gas is heated at constant pressure. Right answer is D because here is "cooled" word.

But cooling is also temperature reduction process, law is not only for the increase in temperature @Mubashir.

Based on Charles's law.
P=Constant.
V/T.
P=Constant.
V/T.

When gas get cooled it starts expanding hence volume increases.
