Answer: The fourth option: mood
Step-by-step explanation:
Sensory details are used in descriptions that affect the five senses: sight, taste, touch, smell, and sound. The intention of using such descriptions is to create a connection with the reader. Readers will be able to "feel" what the characters feel and understand their actions when they can see or smell, for example, what the characters can see and smell.
For instance, if a reader can visualize a dark, somber, scary environment, chances are they will develop a deeper connection with the story by feeling scared as if they are really there, living what the character is living.
