Azure Resource Manager is the correct choice for automating the movement of resources between resource groups. This service provides a management layer for Azure that enables you to create, update, and delete resources in your Azure account. With Azure Resource Manager, you can group related resources together in a resource group, which simplifies the management and automation of those resources.

Specifically, Azure Resource Manager allows you to perform operations on the resources within a resource group as a single operation using templates, and it also supports moving resources between resource groups. This capability is particularly useful when you need to reorganize resources for better management, access control, or cost allocation.

The other services listed do not specifically cater to the automation of moving resources between resource groups. Azure Automation focuses on automating manual processes and orchestrating complex deployment tasks across Azure environments through runbooks. Azure DevOps is oriented towards DevOps practices for software development and delivery, including CI/CD, project management, and collaboration. Azure Functions is a serverless computing service that enables you to run event-driven code without having to manage infrastructure, rather than managing Azure resources directly.
