C=(Q/m Δ T) In isothermal process Δ T=0. Therefore, C is not defined further in isothermal process p V and T both are constants.

Q. Assertion Molar heat capacity cannot be defined for isothermal process.
Reason In isothermal process $p - V$ versus $T$ graph is a dot.

Both assertion and reason are true and reason is the correct explanation of assertion

Both assertion and reason are true but reason is not the correct explanation of assertion

Assertion is true but reason is false.

Both assertion and reason are false.

$C = \frac{Q}{m Δ T}$
In isothermal process $Δ T = 0$ . Therefore, $C$ is not defined further in isothermal process $p V$ and $T$ both are constants.
