Step-by-Step Solution
Solution:
Step 1: Check correct way to raise HTTPException with 403
The correct way is to use raise with status_code=403 and detail message.Step 2: Identify errors in other options
if not is_admin: return HTTPException(status_code=403, detail="Access denied: Admins only") uses return instead of raise, so no error is raised. if not is_admin: raise HTTPException(403, message="Access denied: Admins only") uses wrong keyword 'message'. if not is_admin: HTTPException(status_code=403, detail="Access denied: Admins only") calls HTTPException without raise, so no exception is triggered.Final Answer:
