Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Lithium does not form alum because of its small size and because of its smaller size, lattice energy of formed complex is very low and that is not even stable. Thus both assertion and reason are correct and the reason is the correct explanation of assertion.
