Resource groups in Azure serve as containers that hold related resources for an Azure solution. They help organize resources and provide a means for applying management and security policies.

The correct choice is that resource groups cannot be nested. This means that each resource can belong to only one resource group at any given time, and resource groups themselves do not contain other resource groups. Instead, they directly hold the resources like virtual machines, storage accounts, and databases. This design maintains a straightforward hierarchy in the resource organization, simplifying management and access control.

The other options illustrate valid features of resource groups. For example, resources can indeed be moved between different resource groups, allowing for flexibility in managing where resources are organized based on project needs or department structures. Role-based access control (RBAC) can be applied to resource groups, enabling administrators to manage permissions at the group level, facilitating fine-grained access management. This established hierarchy ensures that permissions can be efficiently administered without needing to set them on an individual resource basis.
