Correct Answer: BDTo move solutions from the development instance to the production instance within the Common Data Service (CDS), there are two effective methods. First, after making necessary changes to the solutions in the development instance, these solutions should be exported as managed solutions. Exporting as a managed solution ensures that the solution can be imported and managed properly in the production environment. Second, in the development instance, you can clone the solution as a patch, make the necessary changes, then export and import this solution into the production instance. Patches allow for incremental updates to solutions without affecting the original solution's integrity. Using both these techniques ensures a smooth and secure transition of solutions between environments.
