The correct answer is C. before the conjunction.
If there is a conjunction between two independent clauses, then the comma will be placed in front of it. For example: <em>We had a lot of fun at the beach, but I feel tired now. </em>
As you can see, the comma is located in front of the conjunction <em>but. </em>Simply placing a comma between the sentences (without a conjunction) creates a run-on sentence, and that is grammatically incorrect.
The right answer for the question that is being asked and shown above is that: "support." The first sentence in the paragraph helps to support the main idea of the paragraph. "...Do you enjoy being out in the fresh air?<span> Does nature restore your spirits?</span><span> ..."</span>
