CH3COO

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 CH3COOH is dissolved in water it gives H+ to water and become CH3COO.
CH3COOH + H2O CH3COO +H3O+
Now this CH3COO is able to accept H+ from H3O+.
So it is base. But actually this base (CH3COO) is derived from an acid (CH3COOH) that' s why CH3COO is conjugate base of (CH3COOH) acid.
