The prefix Epi- denotes which concept?

Explanation:
Epi- denotes location on or upon the surface of something. It’s used when a structure lies on top of or over another surface, as in epicardium (the layer on the heart), epidermis (the outer surface of the skin), and epiglottis (a flap located atop the glottis). That surface-on relationship makes “upon” the best fit among the options. Around would be peri-, across would be trans-, and above would be supra-, none of which describe a surface-on location.
