Solution

The correct option is C $K^{+}, a n d [H F_{2}]^{-}$
Reaction involved in the formation of $K H F_{2}$ shown as
$K F + H F \to K H F_{2}$ or $K^{+} + H F_{2}^{-}$
Compound $K H F_{2}$ formed due to the H-bond $K^{+} F^{-} . . . . H^{δ +} F^{δ -}$
Hence compound $K H F_{2}$ contain $K^{+}$ and $[H F_{2}]^{-}$ ions or species.
Therefore, the correct option is (c).
