The correct answer is Compound sentence
Step-by-step explanation:
The sentence "The body is with the king, but the king is not with the body" is composed of two main clauses: the first one is "The body is with the king", and the second one is "the king is not with the body". Besides this, the clauses are linked by the conjunction "but" which shows the clauses are opposite but have the same importance in the sentence. Also, both clauses express a complete and independent idea.
According to this, the sentence should be classified as a compound because compound sentences include two or more clauses that express a complete idea, and the clauses are linked by a conjunction such as and, or, but, yet, which occurs in the case presented.
