d. HF is an acid and [tex]F^-[/tex] is its conjugate base.

What is acid/ base and its conjugate acid/base?

Whenever an acid donates a proton, the acid changes into a base, and whenever a base accepts a proton, an acid is formed. An acid and a base which differ only by the presence or absence of a proton are called a conjugate acid-base pair.
For example: HCl is an acid and its conjugate base is [tex]Cl^-[/tex].

Given chemical reaction:

[tex]HF(aq) + HPO_4^{2-}(aq)----> F^-(aq) + H_2PO_4^-(aq)[/tex]

In this reaction, HF is an acid and its conjugate base is [tex]F^-[/tex].

Thus out of all the options; the correct option is d.
