a.) ${F}^{-}$(aq)
b.) is $C {O}_{3}^{2 -}$

Explanation:

A conjugate base is an acid that has lost it's proton. So;

in a.)

HF is the acid and the proton goes from the acid to the water. Thus means the conjugate base is the ${F}^{-}$(aq) ion left over.

in b.) THANKS TO ANOR277 FOR THE CORRECTION
the conjugate base of bicarbonate ion, $H C {O}_{3}^{-}$, is $C {O}_{3}^{2 -}$; its conjugate acid is ${H}_{2} C {O}_{3}$...
