Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
HF exists as dimeric molecule due to H bonding and thus shows dibasic nature. Hence it gives two series of salts as $K H F_{2}$ whereas HCl and HBr doesn't show H bonding so they doesn't form series of salts.
