Answer:
The bear ransacked the campers' tents, and it took all of the food.
Step-by-step explanation:
A sentence is made up of an independent clause, thus making it a simple sentence. Now, an independent clause is a clause or group of words that can stand alone and complete a thought.
In the given options, the sentence contains two parts of which both are independent clauses. Now, if there are two independent clauses in a single sentence, they make a compound sentence.
Compound sentences are made by joining the two independent clauses together by using a comma and one of the coordinating conjunctions- for, and, nor, but, or, yet, so (FANBOYS).
Thus, the correct answer will be "The bear ransacked the campers' tents, and took all of the food."
