Which term means outside?

Explanation:
The main idea tested here is how prefixes show position relative to a structure. The term that means outside is extra-, from Latin extrā, indicating beyond or outside. In medical terminology, extra- is used to describe things outside a location, such as extracellular fluid (outside cells) or extramural. In contrast, intra- means inside or within (like intraocular or intramuscular), infra- means below or beneath (such as infracostal), and sub- also means under or below (like subcutaneous). These prefixes describe opposite or different spatial relationships than outside. So extra- is the one that conveys outside, making it the best fit.
