The correct option is C The temple is in the form of a chariot with the Sun God as the charioteer.
As indicated by the verb is, the temple is doing the work in the sentence and, thus, is the subject of the sentence. The rest of the sentence is what is being about the subject, i.e., it is the predicate. Option D is the only one where the subject and the predicate are arranged in correct order and syntax, making complete sense of the meaning of the sentence. Thus, Option D is the correct answer.
