Answer options

• A. yes, Watson services are not visible to run-times running outside of the IBM Cloud environment.
• B. No, IBM Cloud is not required for either the application or for working with the service.
• C. No, any application framework supporting standard REST API invocation can consume a Watson service.
• D. Yes, the networking bindings require that the entire application and Watson service run on IBM Cloud.

Correct answer: D

Explanation

The correct answer is D because the networking bindings of IBM Watson services require both the application and the service to be hosted on IBM Cloud to function properly. Options A and D incorrectly assert limitations on access, while B and C suggest that IBM Cloud is optional, which contradicts the networking requirements of Watson services.
