Solution

The correct option is C Reason is correct but Assertion is incorrect
Isothermal curves don't cross each other. If they cross,there will have same temperature for same P and V which is contradiction.
Hence, Assertion is incorrect
Reason is correct as isotherma change takes place very slowly as temperture of the system must remain constant during whole process.
Hence, option C is correct.
