A{"error": "Bad Request", "code": 400}

B{"status": "error", "code": 400, "msg": "Bad Request"}

D{"error": {"code": 400, "message": "Bad Request", "details": "Missing 'id' parameter"}}

Step-by-Step Solution

Solution:

Final Answer:
{"error": {"code": 400, "message": "Bad Request", "details": "Missing 'id' parameter"}} -> Option D

Quick Trick: Include optional details inside error object for clarity [OK]
