The correct answer is: Applying and enforcing organizational standards and checking compliance across resources.

Azure Policy is the service that lets you define and enforce rules for resource properties so that deployments follow your organization standards. It evaluates resources continuously and reports compliance state, and it can also enforce rules with effects like Audit, Deny, and Modify while you can group policies into initiatives for consistent governance across subscriptions and management groups.

Controlling resource spend by setting budget thresholds and alerts is not correct because cost control and budget alerts are handled by Azure Cost Management and Budgets rather than by Azure Policy.

Assigning roles to users and groups for resource access control is not correct because access control is the responsibility of Azure role based access control and not of Azure Policy.

Packaging resource templates role assignments and policies for consistent deployments is not correct because that describes Azure Blueprints which is used to compose templates role assignments and policies into a single artifact and it complements Azure Policy rather than replacing it.
