Which three object types can a developer import using the Merchant Tools > Content >...

In Salesforce B2C Commerce Cloud, the Import & Export module in Business Manager allows developers to manage various types of data objects related to the site. Specifically:

Content slots (A): These are definable areas within a site where content can be placed and are commonly used to manage dynamic marketing content. They can be imported/exported.

Images and other static assets (B): These include media files and other static resources used in the storefront. They can also be managed through the Import & Export module.

Content assets (E): These are pieces of content that can be reused across different parts of a site, like headers, footers, or promotional content blocks.

On the other hand:

Products (C) and Folders (D) are typically managed through different modules dedicated to catalog and content management respectively, not directly through the Content section of the Import & Export module.

These capabilities align with the platform's functionality to manage digital assets effectively, as detailed in the Salesforce Commerce Cloud documentation.
