The requirements are classic Power Platform ALM requirements:
* the custom connector must be deployed consistently across environments
* it should be editable only in development
The correct design choice is to add the custom connector to Solution1 .
Why B is correct:
* Putting the custom connector inside the solution makes it part of the ALM package
* It can then be exported and imported consistently across environments
* In production, when deployed properly through managed solutions, it is not freely edited there, which supports the requirement that editing happens only in development Why the other options are not correct:
* A. Share the custom connector controls access, not ALM packaging and deployment consistency
* C. Create the custom connector in the default solution is not the recommended ALM approach for contr olled deployment
* D. Add the custom connector to GitHub may help source control, but by itself it does not satisfy Power Platform deployment packaging across environments
