The correct answer is D. “I will see you tomorrow,” said the master.
The other options are incorrect because they do not use the first person singular pronoun “I” to indicate that the master is the one who will be doing the seeing. In option A, the master is the one who will be seen, not the one who will be doing the seeing. In option B, the master is not speaking in the first person, so it is unclear who will be doing the seeing. In option C, the master is using the future progressive tense, which indicates that the seeing will be an ongoing action. However, the sentence in the question indicates that the seeing will be a one-time event.
The sentence “I will see you tomorrow,” said the master, is the most concise and direct way to express the idea that the master will see the listener the next day. It is also the most grammatically correct option.
