Correct Answer:
B. Dependent
This question requires identifying the type of clause based on its function and structure.
- Foundational Fact: A clause is a group of words with a subject and a verb. An independent clause can stand alone as a complete sentence, while a dependent clause cannot; it relies on an independent clause for full meaning and often begins with a subordinating conjunction.
- Correct Answer (B): The clause "until you return" is a dependent clause. It contains a subject ("you") and a verb ("return"), but it begins with the subordinating conjunction "until." This conjunction makes the clause unable to stand alone as a complete thought; it depends on the independent clause "I will wait here" to make sense. Specifically, it functions as an adverbial clause of time.
- Why Distractors are Wrong:
- (A) "I will wait here" is the independent clause in the sentence.
- (C) A noun clause functions as a noun (e.g., subject, object). "Until you return" modifies the verb "wait," indicating when, not acting as a noun.
- (D) An adjective clause modifies a noun or pronoun. "Until you return" modifies the verb "wait," not a noun.
