C. bandwagon appeal
I'm doing a test that asked this question thought I should help :)
I'd say the answer is D.
The definition of the word discern is "1.Perceive or recognize something. ex; I can discern no difference between the two policies."
2. "Distinguish (someone or something) with difficulty by sight or with the other senses. ex; She could faintly discern the shape of a skull."
Make eye contact. The rest of the items listed are not ways to use body language.
I don't know but they will find their place someday just think positive
