Which statement describes Bronsted base?

Explanation:
Bronsted base is a substance that accepts H+ ions. Proton transfer is the defining step: when the base grabs a proton, it forms its conjugate acid. For example, ammonia can accept a proton from water to form ammonium, illustrating proton acceptance. The other ideas describe different concepts: donating H+ would be a Bronsted acid; donating electrons is a Lewis base concept; donating OH- aligns with Arrhenius-base behavior, which is a different framework. So the statement that emphasizes accepting a proton best captures what a Bronsted base is.
