Best Answer Explained in Below-:

The term "vague" refers to something that is not clearly defined, expressed, or understood; it suggests a lack of precision or clarity. Therefore, when looking for an opposite meaning, we seek a word that conveys the idea of being distinctly defined or easily understood. Among the options provided, "clear" is the best choice as it directly implies something that is easily perceivable, free from ambiguity, and understandable.

In contrast, the other options do not serve as suitable antonyms. "Archaic" relates to something outdated or old-fashioned, while "rough" can imply something that is incomplete or unrefined, neither directly opposing "vague." Meanwhile, "haughty" describes an attitude of superiority or arrogance, which is unrelated to clarity or vagueness. Therefore, "clear" stands out as the correct answer, capturing the essence of what it means to be explicit and unmistakable—attributes that are fundamentally opposite to the concept of vagueness.
