The best choice here is (Choice D) 118℉, because the comma is needed to properly connect the clauses and maintain the flow of the sentence.

So the corrected sentence would read:

"In the summer, daytime temperatures in the Sonoran desert can reach up to 118℉, so many desert animals are nocturnal, preferring to avoid activity under the scorching sun."
