Comprehensive and Detailed 100to 150 words of Explanation From Copado Extension builder topics:

Custom Metadata Types are needed in the Copado Extension creation process to create the configuration record that links the extension package to its static resource. Option B is correct, although the option appears to contain a wording issue and should be understood as creating the required static resource-related configuration. In Copado Extensions, selected Function or Job Template records are generated into a JSON file and stored in a static resource. A custom metadata record then points to that static resource so Copado knows which packaged extension data should be processed after installation. Option A describes the JSON generation step, but that is performed by the Copado Extensions tool rather than the reason for creating Custom Metadata Types. Options C and D are not the correct purpose.
