Question

identify the independent clause.
choose 1 answer:
a are you sure
b that you are sure

Explanation:

An independent clause can stand alone as a sentence, having a subject and a predicate. Option A "Are you sure" has a subject ("you") and a predicate ("are sure") and can function as a question on its own. Option B "that you are sure" is a dependent clause (a subordinate clause introduced by "that") and cannot stand alone as a complete sentence.

Answer:

A. Are you sure
