Final answer:
The sentence in question is a compound-complex sentence, as it contains two independent clauses and one dependent clause. The correct answer is option C.
Step-by-step explanation:
The sentence 'Whenever we have an ice storm, the twins go skating, and I enjoy the peace.' is considered a compound-complex sentence. This type of sentence includes at least two independent clauses and one or more dependent clauses. In this case, 'the twins go skating' and 'I enjoy the peace' are the two independent clauses that could stand on their own as sentences, and 'Whenever we have an ice storm' is the dependent clause that cannot stand alone.
