Solution

Air filled balloon is kept inside the glass jar fitted with a vacuum pump. The size of the balloon will increase when air is taken out with the help of vacuum pump from the jar.
Boyle's law supports the answer.
" When temperature and amount of gas is constant, the volume of a given mass of gas is inversely proportional to its pressure."
$V \propto \frac{1}{P}$
