A
(b) or (c) depending on the temperature.
💡 Explanation:
For a diatomic gas like hydrogen, the molar specific heat at constant volume depends on the temperature. At low temperatures, only translational degrees of freedom are active (3R/2). At moderate temperatures, rotational degrees of freedom are active (5R/2). At very high temperatures, vibrational degrees of freedom may also contribute (7R/2).
