Read the sentence.

Which of these identifies the entire subordinate clause in this sentence?

-my friend Sara is home-schooled

-Although most of my friends

-Although most of my friends go to public school

-Sara is home-schooled

I believe the correct answer is the third option: Although most of my friends go to public school.

Subordinate clause is the dependable clause, which means that it can’t stand alone as it doesn’t express the full information. These clauses are introduced by the subordinate conjunction or relative pronoun (although, that, once, until etc.) and a comma. In this case, the subordinate clause is adverbial clause (has a function of an adverb) "Although most of my friends go to public school," which is introduced with the subordinate conjunction although and divided with a comma from the main clause as it is inverted.
