Choose the sentence that has an Adjective Clause.

The correct answer is Option (2) → He laughs best who laughs last.

An adjective is a word that describes a noun or a pronoun, for example a tall tree, the food is tasty.

Adjective clause:

• An adjective clause describes a noun or pronoun, as an adjective does.
• It usually begins with a relative pronoun (who, which, that, whom, whose) and answers the question "which one?".
• This sentence: who laughs last describes the pronoun He: the man who laughs last is the one who laughs best.

Why the Other Options are Incorrect?

Option 1: I expect to get a prize. — Incorrect. "to get a prize" is an infinitive phrase acting as the object of "expect". It has no subject and verb of its own, so it is not a clause.

Option 3: He confessed to his guilt. — Incorrect. This is a simple sentence. "To his guilt" is a prepositional phrase.

Option 4: You may sit wherever you like. — Incorrect. "wherever you like" tells where you may sit. It modifies the verb "sit", so it is an adverb clause of place.

Contrast: an adjective clause describes a noun or pronoun (who laughs last describes He). An adverb clause modifies a verb (wherever you like modifies sit).
