Which of the following entails descriptions that appeal to the senses?

Imagery is the correct answer because it specifically refers to the use of descriptive language that evokes sensory experiences in the reader's mind. This can include visual descriptions that allow one to "see" what is being depicted, as well as appeals to other senses such as sounds, smells, tastes, and tactile sensations. Writers often utilize imagery to create vivid and engaging scenes that enhance the emotional depth and atmosphere of their work, helping readers to experience the text more fully.

In contrast, symbolism relates to using symbols to represent ideas or concepts, which does not inherently involve sensory experiences. Theme refers to the underlying message or main idea of a piece of literature, and while it may be conveyed through imagery, it is not itself a descriptive technique. Metaphor involves comparing two unlike things without using "like" or "as," and while it can create strong imagery, its primary function is to convey meaning rather than to focus on sensory details.
