Correct Answer: Option D
Explanation

At constant T, P1 V1 = P2 V2.

Let P1 = P0 and V1 = V0, then solve accordingly.

As pressure is varies inversely as volume according to:

Boyle's law, also referred to as the Boyle–Mariotte law, or Mariotte's law, is an experimental gas law that describes how the pressure of a gas tends to decrease as the volume of the container increases.

As volume is reduced by one-fifth; pressure will increase by five times.
