Question

Explanation:

A compound sentence combines two independent clauses with a conjunction. The option "karate, so he doesn't have time for theater rehearsals" has two independent clauses ("Ruben takes karate" and "he doesn't have time for theater rehearsals") connected by "so", forming a compound sentence. Other options are simple or complex with phrases, not two independent clauses.

Answer:

B. karate, so he doesn't have time for theater rehearsals
