B. We are going to pick the peppers
As you may know, an independent clause is basically a clause that is a complete sentence (or the portion of a clause that can stand on its own. Of all the possible responses, and with that mind, the only option that contains a complete thought is “B. We are going to pick the peppers.” The first option, “A,” could be a bit misleading because it kind of looks like a complete sentence, but it leaves things hanging. “We are going to…” Well, we are going to what? In the future, when trying to determine which clause within a sentence is an independent clause, be on the lookout for which clause is a complete thought and can stand on its own making the most sense.
