Gas Laws & Ideal Gas Equation

For hydrogen gas $C_P - C_V = a$ and for oxygen gas $C_P - C_V = b$ , so the relation between $a$ and $b$ is given by

Show answer and solution

Answer: (d)

Mayer's relation for molar specific heats of any ideal gas: $C_P - C_V = R$ .
It does not depend on the gas, so $a = R$ for hydrogen and $b = R$ for oxygen.
So the answer is (d) $a = b$ .
