I go for A. It is absolute clause.

Wait for the OA.

Let's break the sentence in two parts: Part 1: The presence...in Ohio Part 2: Their numbers...warm temperatures.
Now the part 1 is a complete sentence on its own whereas part 2 starts with a possessive suggesting a dependent clause would come. Also comma + possessive is a dependent clause and two independent clauses must not be joined with simply a comma. Hence, any option that can make part 2 an independent clause must be eliminated (B,C, D.)

Between A and E, A is our clear choice as "and" in E makes the sentence illogical and meaningless.

Hence, A is correct

Hope it helps!!

I also chose D as the correct answer but now i realized if we put D in the original sentence the whole sentence becomes a run on sentence. Both the clauses are separated only by a comma(have increased will become the verb). If we use verb+ing it modifies the sentence and doesn't form a runon sentence.

Please correct me if i m wrong
