Three moles of an ideal gas undergoes a cyclic process ABCA as shown in the figure. The pressure, volume and absolute temperature at points $\mathrm{A}, \mathrm{B}$ and C are respectively $\left(\mathrm{P}_1, \mathrm{~V}_1\right.$, $\left.T_1\right),\left(P_2, 3 V_1, T_1\right)$ and $\left(P_2, V_1, T_2\right)$. Then the total work done in the cycle ABCA is (R- Universal gas constant).

• A

  $\mathrm{RT}_1[3 \ln (3)+2]$
• B

  $\mathrm{RT}_1[3 \ln (2)]$
• C

  $3 \mathrm{RT}_1(\ln 3)$
• Correct answer
  D

  $\mathrm{RT}_1[3 \ln (3)-2]$

Hence, the correct answer is option: 'D'.
