Let us know what you decide.

is it C

Yes, it's C.

To combine the two sentences into one compound sentence, you can use coordinating conjunctions like "and," "or," or "but."

Looking at the options provided:

A. The sentence "The dog followed the rabbit when it jumped into the bushes" uses a subordinating conjunction ("when") instead of a coordinating conjunction, so it does not represent a compound sentence.

B. The sentence "After the rabbit jumped into the bushes, the dog followed it" uses a subordinating conjunction ("after") instead of a coordinating conjunction, so it also does not represent a compound sentence.

C. The sentence "The rabbit jumped into the bushes, and the dog followed it" uses the coordinating conjunction "and" to join the two independent clauses ("The rabbit jumped into the bushes" and "the dog followed it"), making it a compound sentence.

D. The sentence "The dog and the rabbit jumped into the bushes" combines the subjects of the two sentences, but it does not express the sequence of events or indicate that the dog followed the rabbit, so it does not represent a correct compound sentence.

Therefore, the correct answer is C - "The rabbit jumped into the bushes, and the dog followed it."
