Answer:
A. Synesthesia
Step-by-step explanation:
Synesthesia is a perceptual phenomenon in which stimulation of one sensory or cognitive pathway leads to involuntary experiences in a second sensory or cognitive pathway. You can incorporate the use of synesthesia as a rhetorical device in your own writing. If you can blend two of the five senses—sight, hearing, touch, taste, smell—together in a phrase or a sentence, then you'll be able to describe common forms of synesthetic perceptions. Synesthesia in literature or poetry is a literary device that writers can use to create interest in the work.
