Explanation:

To link a claim and counterclaim about renewable energy and its cost, a complex sentence is suitable as it can show the relationship (like concession, cause - effect) between the two ideas. A compound sentence mainly contrasts or joins independent clauses, a simple sentence can't show the relationship well, and repeating the main idea doesn't use syntax for linking. So the correct option is the one about the complex sentence explaining the relationship.

Answer:

The author uses a complex sentence that explains the relationship between the two ideas.
