Answer:
The correct naswer is D.
Step-by-step explanation:
Stream of consciousness is a style of writing that shows thoughts and feelings as they pass through the mind of the character. It's a flow of ideas, disorganised with no clear or complete structure. It's used to give the reader the idea that he/she is in the character's mind.
In the example given in the question, it shows the person's reactions about getting wet. His/her line of thought is: It's raining, he/she doesn't want to get wet because that's uncomfortable. Then, all of a sudden he/she stops talking about rain and mentions a seat. The person likes that seat but he/she should move. All of a sudden, he thinks that it's an important day. We don't know why. This shows different random thoughts and feelings that reflect the character's thought process. Besides, there's lack of grammatical constructions. An example of this is the phrase Kind of like that seat.
All in all, in this example you can find a "stream" of ideas that comes to the mind of the narrator and he writes them down as they come, disorganized and written with no conventional structures.
