#CH_3COO^-#

Explanation:

According to Lewis Concept 'a substance which donates #H^+# to other is an Acid and a substance which accepts #H^+# is a Base.
When #CH_3COOH# is dissolved in water it gives #H^+# to water and become #CH_3COO^-#.
#CH_3COOH# + #H_2O# #rightleftharpoons# #CH_3COO^-# +#H_3O^+#
Now this #CH_3COO^-# is able to accept #H^+# from #H_3O^+#.
So it is base. But actually this base (#CH_3COO^-#) is derived from an acid #(CH_3COOH)# that' s why #CH_3COO^-# is conjugate base of #(CH_3COOH)# acid.
