Universal Containers' support team wants to use Salesforce Knowledge to allow customers and the support team to have access to the product…

Data categories are the primary feature for organizing, filtering, and controlling access to Salesforce Knowledge articles. They allow administrators to create a logical hierarchy to classify articles. This structure enables both internal support users and external customers to find relevant information easily. Visibility settings for data categories can be configured by user profile, allowing different audiences (like customers vs. support team) to see only the articles relevant to them. This directly addresses the need for global documentation with varied access levels.

A. Enable the Case Feed: This feature relates to the user interface for managing cases and does not control the organization or visibility of Knowledge articles.
B. Create article types: This is a feature of Salesforce Classic Knowledge. In Lightning Knowledge, record types serve this function to define article structure, not for classification and visibility.
D. Setup record types and page layouts: Record types in Lightning Knowledge define the structure and fields for different kinds of articles but do not control the classification hierarchy or audience visibility.
