For an ideal gas, a cyclic process ABCA as shown in $\mathrm{P}-\mathrm{T}$ diagram, when presented in $\mathrm{P}-\mathrm{V}$ plot, it would be

• A

  
  
• B

  
  
• Correct answer
  C

  
  
• D

  
  

Solution

$\mathrm{AB} \rightarrow$ Isobaric compression $B C \rightarrow$ Isothermal expansion CA $\rightarrow$ Isochoric process $\therefore \quad$ Correct $\mathrm{P}-\mathrm{V}$ diagram is

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