From the figure shown for a thermodynamic system, match the curves with their respective thermodynamic processes. (P - Pressure and V - volume)

Curve	Process
I	a) Adiabatic
II	b) Isobaric
III	c) Isochoric
IV	d) Isothermal

• Correct answer
  A

  I-c, II-a, III-d, IV-b
• B

  I-c, II-d, III-b, IV-a
• C

  I-d, II-b, III-a, IV-c
• D

  I-a, II-c, III-d, IV-b

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