Assertion-Reason▾

### Assertion (Ꭺ)

The isothermal curves intersect each other at a certain point.

### Reason (Ꭱ)

The isothermal change takes place slow; so the isothermal curves have very little slope.

Ꭺ is false but Ꭱ is true

b.

Ꭺ is true but Ꭱ is false

c.

Both Ꭺ and Ꭱ are true but Ꭱ is NOT the correct explanation of Ꭺ
