Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
Hydrofluoric acid is a dibasic acid due to hydrogen bonding. It exists as a dimer $(H F)_{2}$ .
Hence, it forms two series of salts ${K H F}_{2}, K_{2} F_{2}$ .
Thus, both Assertion and Reason are correct and Reason is the correct explanation for Assertion
