a) conjugate base: $N {H}_{3}$
b) conjugate acid: ${H}_{2} P {O}_{4}^{-}$

Explanation:

I think in your question you meant to ask for the conjugate base of $N {H}_{4}^{+}$ and the conjugate acid of $H P {O}_{4}^{2 -}$

$H P {O}_{4}^{2 -}$ has the ability of being both an acid and a base. If it's considered an acid, the conjugate base would be $P {O}_{4}^{3 -}$. If it's considered the base, the conjugate acid would be ${H}_{2} P {O}_{4}^{-}$.

Conjugate bases result once an acid donates its hydrogen ion.

Conjugate acids result once a base donates its hydrogen ion.
