Select the most appropriate ANTONYM of the given word.

CASUAL

Planned

The correct answer is option 1. Planned.

"Casual" typically means relaxed, informal, or not planned.

The antonym we're looking for should describe something that is formal or intentionally arranged.

"Planned" fits this description perfectly. It means intentionally arranged or prepared in advance, contrasting with "casual," which implies something that is not intentionally arranged or formal.

Therefore, "planned" is the appropriate antonym for "casual" because it represents the opposite characteristic—intentionally arranged or formal instead of relaxed or informal.
