Correct answer: 1

  1. We match each thermodynamic process with its defining constant quantity.

  2. Isothermal process:

    • In an isothermal process, temperature remains constant.
    • So, (a)→(ii)(a) \to (ii)(a)→(ii).

  3. Isochoric process:

    • In an isochoric process, volume remains constant.
    • So, (b)→(iii)(b) \to (iii)(b)→(iii).

  4. Adiabatic process:

    • In an adiabatic process, there is no heat exchange with surroundings, i.e. heat content transferred is zero / effectively taken as constant in the given matching.
    • So, (c)→(iv)(c) \to (iv)(c)→(iv).

  5. Isobaric process:

    • In an isobaric process, pressure remains constant.
    • So, (d)→(i)(d) \to (i)(d)→(i).

  6. Therefore, the correct matching is:

    (a)−(ii),(b)−(iii),(c)−(iv),(d)−(i)(a)-(ii),\quad (b)-(iii),\quad (c)-(iv),\quad (d)-(i)(a)−(ii),(b)−(iii),(c)−(iv),(d)−(i)

  7. Comparing with the options, this corresponds to Option 1.

  8. Comparison with stored answer:

    • Stored correct answer = 1
    • Derived answer = 1
    • They agree.
