Answer:
C) A narrator
Step-by-step explanation:
The flow of consciousness, in a nutshell, is nothing more than an attempt to write by simulating the order - or disorder - of thoughts, using the breaking of grammatical rules.
The term "Flow of Consciousness" was coined by psychologist William James, presented in his principal work Principles of Psychology (1890). William James coined this term to demonstrate the continuity of mental processes, which does not manifest fragmentarily, in successive pieces, but in a continuous "flow" of thoughts. The literature has appropriated this term to name literary techniques in which there is an attempt to represent the metal processes and thoughts of the characters as they would occur in their minds. In this case, there is no narration in the story. Then we can conclude that the correct answer to your question is the letter C.
