Which Salesforce customization provides a single view of a case's related items and edits?

• A. Create a custom-related list on the case.
• B. Create a custom report.
• C. Create a custom view on the Case tab.
• D. Create a custom Visualforce page.

Answer: (A)

Providing a single view of a case’s related items and enabling edits is best achieved by adding a custom-related list to the Case page layout. A related list surfaces records that are connected to the Case—such as activities, comments, attachments, and other linked objects—directly on the case record. This setup consolidates everything in one place, so users can see all pertinent items without switching pages, and they can edit inline in the list if inline editing is enabled.

Other options don’t deliver the same per-case, consolidated view: a custom report summarizes data across many records rather than showing the related items for a single case; a custom view on the Case tab displays multiple cases, not the items tied to one case; a custom Visualforce page could recreate this interface but requires more development work and maintenance.
