Answer:
C. The Time Traveller.
Step-by-step explanation:
H. G. Wells' science fictional story "The Time Machine" is about a dystopian world revolving around the future of humanity. The story shows humanity through the characters of the Elois and the Morlocks, representing the different races of humans in the future.
The given quote "You must follow me carefully. I shall have to controvert one or two ideas that are almost universally accepted." is found in the first chapter of the book. This line is spoken by the Time Traveller who requested the other characters including the speaker, to pay attention to what he has to say and show.
Thus, the correct answer is option C.
