Explanation

Option B is correct because it uses the proper Apache Velocity Template Language (VTL) syntax for API Gateway mapping templates, checking a query string parameter ('scope') using $input.params() and returning appropriate HTTP status codes (200 for success, 500 for error). For mock integrations in API Gateway, the integration request mapping template must return a statusCode that maps to a configured integration response, and using $input.params() to read request parameters to conditionally set the statusCode is the standard, supported pattern. The 200 and 500 status codes represent realistic mock responses that would be configured in the integration responses.
