The prefix extra- indicates which spatial relation?

• A. Inside
• B. Outside
• C. Beyond

That makes the spatial relation it conveysOutside. For comparison, inside would be indicated by a prefix like intra- or endo-, and terms meaning across or beyond use different prefixes depending on context. So outside is the best fit for extra-.
