Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
In Class Mammalia, teeth are of different types (heterodont) and are embedded in the socket of the jaw (thecodont). These are developed twice during the lifetime of the animal (diphyodont), i.e., milk and permanent teeth. Therefore, the reason is not correct for the given assertion. So, the correct answer is 'B'.
