a) conjugate base: #NH_3#
b) conjugate acid: #H_2PO_4^(-)#

Explanation:

I think in your question you meant to ask for the conjugate base of #NH_4^+# and the conjugate acid of #HPO_4^(2-)#

#HPO_4^(2-)# has the ability of being both an acid and a base. If it's considered an acid, the conjugate base would be #PO_4^(3-)#. If it's considered the base, the conjugate acid would be #H_2PO_4^(-)#.

Conjugate bases result once an acid donates its hydrogen ion.

Conjugate acids result once a base donates its hydrogen ion.

Hope this helps.
