Which characteristic is true about business groups in MuleSoft?

The characteristic that is true about business groups in MuleSoft is that each group has a separate client ID and client secret.

Business groups are designed to segment resources, permissions, and configurations within a larger MuleSoft organization. By having separate client IDs and client secrets for each business group, it allows for fine-grained control over access and usage linked to that specific group. This is especially important for maintaining security and ensuring that different teams or projects can work independently without interfering with the configurations or data of others. The separation of credentials also simplifies the management of APIs and allows for tailored access control, thus enhancing the overall governance of the organization's assets.

The other characteristics do not accurately reflect how business groups function or are managed in MuleSoft, as they typically don't facilitate resource sharing among all users, do have environmental configurations, and the deletion of a business group can affect associated resources.
