Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Alkali metals have weak metallic bonding due to the presence of only a single valence electron in them. Thus, there melting point is low.
Thus, both Assertion and Reason are correct, but the Reason is not the correct explanation of the Assertion.
