Which is a Bronsted base example?

Explanation:
A Bronsted base is a substance that accepts a proton (H+). Ammonia fits this role nicely because it has a lone pair on nitrogen that can attract a proton to form the ammonium ion: NH3 + H+ → NH4+. This shows base behavior—taking in a proton. In contrast, HCl and CH3COOH donate protons, so they are Bronsted acids. Water is amphiprotic and can act as a base in some contexts by accepting a proton to form H3O+, but the classic, unambiguous example here is ammonia acting as a Bronsted base.
