The correct answer is: C. She was spoken to by the official on duty.
The other options are incorrect because they do not correctly reflect the order of the words in the original sentence. In the original sentence, the word “she” comes before the word “spoke.” This means that the person who spoke is “she” and the person who was spoken to is “the official on duty.”
Option A is incorrect because it reverses the order of the words. In option A, the word “official” comes before the word “spoke.” This means that the person who spoke is “the official” and the person who was spoken to is “she.”
Option B is incorrect because it adds the word “on duty” after the word “spoke.” This means that the person who spoke is “she” and the person who was spoken to is “the official on duty.” However, the word “on duty” is not necessary in this sentence.
Option D is incorrect because it changes the meaning of the sentence. In option D, the word “she” is the subject of the sentence. This means that the sentence is about “she” and not about the official on duty.
