What is a synonym for "remonstrate"?

The term "remonstrate" means to express earnest disagreement or protest. It involves presenting objections or reasons against something, essentially arguing a point. Therefore, "argue" is a fitting synonym because it captures the essence of engaging in discussion or contention to express different viewpoints or to oppose a certain idea or action.

The other choices do not align with the meaning of "remonstrate." "Support" implies agreement or endorsement rather than opposition. "Encourage" suggests a positive reinforcement or motivation towards an action, while "dismiss" indicates a rejection or disregard, which does not embody the act of actively stating a disagreement or protest as "remonstrate" does.
