A vessel of volume ‘V’ contains an ideal gas at a pressure ‘${\mathrm{P}}_0$ ’. The gas being removed from the vessel by means of piston pump with single stroke  by volume $\frac{\mathrm{V}}{4}$  . The pressure of the gas inside the vessel after $3^{\mathrm{rd}}$ stroke of the piston is 

• A

  $\frac{{\mathrm{P}}_0}{3}$

• B

  $\frac{64{\mathrm{P}}_0}{125}$

• C

  $\frac{27{\mathrm{P}}_0}{64}$

• D

  $\frac{8{\mathrm{P}}_0}{27}$
