Answer:
D. compound-complex sentence.
Step-by-step explanation:
A compound sentence comprises two simple sentences/independent clauses joined by a coordinating conjunction or comma or semicolon.
A complex sentence comprises a simple sentence/independent clause and a dependent or subordinate clause.
Therefore, a compound-complex sentence contains at least two independent clauses and at least one dependent clause. A compound- complex sentence is a compound sentence with at least a dependent, or subordinate clause.
Breaking down the given sentence;
Key:
He enjoys hiking in the forest - Independent clause
Kenny likes the view that he gets from the top of the mountain - Independent clause
On the other hand - dependent clause
and - coordinating conjunction
Therefore, the sentence "Kenny, on the other hand, likes the view that he gets from the top of the mountain, and he enjoys hiking in the forest." is a compound-complex sentence.
