D . More modules and metadata can be added to Salesforce B2B Commerce.

Answer: D

Explanation:

More modules and metadata can be added to Salesforce B2B Commerce by creating custom configuration settings. Configuration settings are custom settings that store various values and parameters that affect the functionality and appearance of the storefront. They are organized into modules, which group related settings together. To create a custom configuration setting, the user needs to create a custom setting record in Salesforce and specify its module, name, value, and description. The custom setting will then appear in CCAdmin under the specified module.
