    c. F1-

    Explanation:

    In this chemical reaction the expression is:

    HF + NaF → NaHF2

    The ion that always keep the negative charge is the fluorine with a - 1, if in this mixture there is more positive ions (H1+) the negative ion (F1-) will join with them.

    Remember that also the Cl1 - will be free, but the fluorine is more reactive than the fluorine.
