- Unwisely
- Wise,
- Happy
- None of these
The correct answer is “unwisely” because it is the only word among the options that is explicitly an adverb. It is formed by adding the suffix “-ly” to the adjective “unwise.” This structure is a clear marker of an adverb, which is used to modify verbs (e.g., “He acted unwisely”). The other options, “wise” and “happy,” are adjectives used to describe nouns (e.g., a wise decision, a happy person). Since the question asks for an adverb, “unwisely” is the correct choice.
