Select the most appropriate synonym of the given word. BRASH

The correct answer is option 3. Self-confident.

"Brash" typically describes someone who is overly confident or assertive to the point of being somewhat rude or aggressive. A person who is brash might act without considering the consequences or without tact. Therefore, "self-confident" is the most appropriate synonym because it also describes someone who is sure of themselves, although it carries a more positive connotation than "brash." Both terms suggest a high degree of confidence, but "self-confident" implies a more controlled and positive demeanor compared to the potentially negative implications of being "brash."
