assumption is true but reason is false

Answer 2

For the given question regarding crows -

(c) Our Assertion is false but the Reason is true.

Crows are birds which can be commonly seen. They are black in colour, but not all the crows are black. They are grey as well as cream in color too.

Not much is known about biological adaptation of crow as black but the theory is their adaptation is to identify their species.

Same color for same species. Black color may also result due to industrial pollution.
