Answer:
C. I had goose bumps, and the hairs on my arms were standing straight up.
Explanation:
Sensory detail will be based on the senses- namely taste, touch, smell, sound and sight. And any sentence that shows or indicate any of these five senses will be exhibiting the sensory details of the passage.
The sentence that shows this sensory detail in "The Amusement Park" by Paolo is when he describes his "goosebumps". The literal feeling of having one's hairs stand straight up, with the goosebumps shows the sensory feeling of the author when he visited the roller coaster.
