@GetMapping("/user")
public ResponseEntity getUser() {
    return "User data";
}

AURL path should be /users

ResponseEntity is a wrapper object; returning a String directly causes a type mismatch error.
Final Answer:
Return type ResponseEntity requires a ResponseEntity object, not a String -> Option B
Quick Check:
ResponseEntity return must match object type [OK]

Quick Trick: Return ResponseEntity object when declared as return type [OK]
