- The phrase "Whether he like it or not" functions as an adverb clause because it modifies the main verb "has to attend" by indicating the condition under which the action occurs.
- It answers the question "Under what condition does he have to attend the meeting?" — namely, regardless of his preference.
- Although it begins with "whether," which can introduce noun clauses, in this context it introduces a concessive adverbial idea (similar to "even if"), making it an adverb clause.
- It is not a noun clause because it doesn’t act as a subject, object, or complement of the main clause.
- It is not an adjective clause because it doesn’t modify a noun or pronoun directly.
- Therefore, the correct answer is C: Adverb Clause.
