Solution

The correct option is D Both Assertion and Reason are incorrect
Assertion
The isothermal curves intersect each other at a certain point.
Reason
The isothermal changes takes place rapidly, so the thermal curves have very little slope.

To carry out isothermal process, a perfect gas is compressed or allowed to expand very slowly. Isothermal curves never intersect each other as they have very little slope
hence both Assertion and Reason are incorrect
