Which prefix would indicate something around or surrounding?

• A. Peri-
• B. Para-
• C. Inter-
• D. Intra-

Answer: (A)

The main idea here is understanding how prefixes describe spatial relationships. peri- means around or surrounding something. That’s why it’s used for structures that envelop another part, like the pericardium around the heart or the periosteum around a bone. This sense of encircling matches the prompt asking for something around or surrounding.

Other prefixes describe different relations: para- means beside or near, not encircling; inter- means between; intra- means within. So para- would indicate “near” rather than surrounding, inter- indicates the space between two things, and intra- indicates being inside something.
