Correct answer · Option 2
A-(II), B-(I), C-(IV), D-(III)
Explanation
Adiabatic: \( q = 0 \implies \Delta U = w_{\text{ad}} \) (A-II). Isochoric: \( \Delta V = 0 \implies \Delta U = q_v \) (B-I). Isobaric: \( q_p = \Delta H \) (C-IV). Isothermal free expansion: \( w = 0, q = 0, \Delta U = 0 \) (D-III).
