Change Membership Type of Group from Assigned to Dynamic User

C.

The correct answer is D. the Microsoft Teams admin center.

Explanation: In Microsoft Teams, there are two types of groups - static groups (Assigned) and dynamic groups (Dynamic User). Static groups are manually managed, and membership doesn't change automatically. In contrast, dynamic groups are rule-based, and membership is automatically updated based on criteria specified in the rule.

To change the membership type of a group from Assigned (static) to Dynamic User, you need to use the Microsoft Teams admin center. Here are the steps to follow:

1. Sign in to the Microsoft Teams admin center (https://admin.teams.microsoft.com/).
2. In the left navigation pane, select Teams > Teams policies.
3. Select the policy that contains the group you want to modify, and then select Edit.
4. Under Membership type, select Dynamic User, and then select Save.

Note that when you change the membership type of a group from static to dynamic, the existing members will be removed, and the group will start to follow the membership rules specified in the dynamic membership rule.

Option A (Active Directory Users and Computers) is not the correct answer because it is used to manage users, computers, and groups in the on-premises Active Directory domain, but it does not have the capability to manage Microsoft Teams membership types.

Option B (the Microsoft Teams client) is not the correct answer because it is used to access and use the Teams application, but it does not have the capability to manage Teams membership types.

Option C (the Azure Active Directory admin center) is not the correct answer because it is used to manage user accounts and identity in Azure Active Directory, but it does not have the capability to manage Teams membership types.
