Your Best Friend Is a Big Fan of Essential Oils

Your best friend is a big fan of essential oils. While studying for an exam, she likes to put citrus orange in her diffuser while she works. Having just read this chapter of your book, what recommendation do you make to her for her future studies and exam performance?

A) You suggest that she use lemon oil, as it is more closely associated with improved memory retrieval.
B) You suggest that she put a small amount of oil on the pencil she will use to take her exam so that she can still smell the orange during the test.
C) You suggest that she use orange at home but bring lavender to the exam, as that will relax her.
D) You suggest that she only use orange oil during the exam, and not at home while studying.
