5 moles of a gas is allowed to pass through a series of changes as shown in the graph, in a cyclic process. The processes $\mathrm{C} \rightarrow \mathrm{A}, \mathrm{B} \rightarrow \mathrm{C}$ and $\mathrm{A} \rightarrow \mathrm{B}$ respectively are

• A

  Isothermal, Isochoric, Isobaric
• B

  Isochoric, Isobaric, Isothermal
• C

  Isobaric, Isochoric, Isothermal
• Correct answer
  D

  Isothermal, Isobaric, Isochoric

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