The correct answer is: Option C. Use precise, sensory language.
An elaboration is the process of presenting information in detail. Regarding a personal narrative, this process can be included by detailing the information one already has.
It is also a good suggestion to use sensory language, providing the reader a mean to familiarize with the author's work without the need of more blocks of text - which makes it more appealing to those who don't enjoy getting lost among a sea of words.
