Which acid has the strongest conjugate base in aqueous solution?

I have the right answer but don't know why it's right and why the rest are wrong. Thank you!

Answer 1

Answer #1

If the conjugate base is strong iff its acid is weak.

Among the given HF is the weakest acid.

So HF has the strongest conjugate base H₂F⁺ in aqueous solution

Therefore option (A) is correct
