The prefix that indicates a position 'under' is typically "sub-". This prefix comes from Latin, where it means "under, below, or beneath." For instance, in terms like "submarine," it refers to something that operates below the surface of the water.

In contrast, "hypo-" also indicates something that is below, but it generally refers to a deficiency or a lower level, particularly in medical contexts, such as "hypoglycemia," meaning low blood sugar. However, in many usage contexts, "sub-" is more directly aligned with the notion of position beneath something.

"Pro-" indicates favoring or in support of something, unrelated to positioning, while "retro-" refers to backward or past in terms of direction or time. Thus, the best choice for a prefix indicating a position 'under' is "sub-."
