Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
De - Brogile wavelength associated with gas molecules varies as $λ α \frac{1}{\sqrt{T}}$ . Also, thus it depends on the temperature. Thus, the Reason and Assertion are true but the Reason is not the correct explanation for the Assertion.
