In Nutanix Prism Central, categories allow administrators to group and organize entities for management, automation, and policy enforcement.

Alerts (Option B) can be categorized to group similar system events and create filtering rules.

Virtual Machines (Option C) can be categorized to apply security policies, automation tasks, and resource allocation rules.

Option A (Storage Containers) cannot be categorized in Prism Central. Storage policies apply at the container level but are not managed via categories.

Option D (ISO Images) cannot be categorized because ISOs are static objects, not active entities.
