(C) with
(D) None of these
🧠 Explanation:
- The correct preposition used with the adjective "different" is usually "**from**" in standard English.
- We say someone is "different from" others, not "different of" or "different with."
- The structure “different from” compares one person or thing to another in terms of contrast.
- Therefore, the grammatically correct sentence is: "How is he different from the people around him."
