In what type of Salesforce construct are Storefront themes stored?
A . Visualforce Pages

Answer: C

Explanation:

According to the Storefront Themes page, storefront themes are collections of files that define the look and feel of your storefront. Storefront themes are stored as static resources in Salesforce. Static resources are files that can be referenced by Visualforce pages or Lightning components. Therefore, option C is correct. Options A, B, and D are false because storefront themes are not stored as Visualforce pages, attachments, or custom objects.
