Conjugate base hpo4 2.

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 ⇌ CH 3COO− + H 3O+. Now this CH 3COO− is able to accept H + from H 3O+. So it is base.
