another source, and I agree that answer is D https://www.cisco.com/c/en/us/support/docs/routers/sd-wan/214509-troubleshoot-control-connections.html#toc-hId-1981257189 If the serial number is not present on the controllers for a given device, the control connections fail. When you troubleshoot such a problem, ensure that the correct serial number and device model was configured and provisioned on the PnP portal (software.cisco.com) and vManage.
