The correct choice for automating alerts when new Azure subscriptions are added to an Enterprise Agreement is Azure Monitor action groups. Action groups are a critical component of Azure Monitor that enable you to define specific responses when certain alerts are triggered. In the context of monitoring for new Azure subscriptions, action groups can be configured to send notifications via different channels such as email, SMS, or even trigger automated workflows through Azure Logic Apps or Azure Functions.

Using action groups allows for real-time alerting, ensuring that relevant stakeholders are notified immediately when a new subscription is added. This proactive approach enhances the governance and visibility of resources within an organization, which is crucial in an enterprise environment.

While other options like Azure Policy, Azure Resource Manager templates, and Azure Automation runbooks play significant roles in managing and deploying resources within Azure, they do not directly cater to the requirement of generating alerts based on the creation of new subscriptions. Azure Policy is more about enforcing compliance rules, ARM templates are used for resource deployment and management, and Azure Automation runbooks are typically used for automating tasks rather than setting up monitoring alerts. Thus, Azure Monitor action groups is the most appropriate choice for this scenario.
