A Microsoft 365 Copilot license is an add-on subscription that must be assigned to an individual user account. The primary and direct purpose of this assignment is to unlock and enable the AI-powered Copilot features within the suite of Microsoft 365 applications, such as Word, Excel, PowerPoint, Outlook, and Teams. Without this license, the Copilot functionalities will not be available to the user, even if they have a base Microsoft 365 E3/E5 license. The license is the key that grants access to the service.

B. Monitoring usage is an administrative task that is possible after a license is assigned and used, but it is not the primary purpose of the license itself.

C. Assigning an add-on Copilot license is an additional cost per user, which increases, rather than reduces, the organization's overall subscription costs.

D. Licenses grant access to software features, not administrative roles. Assigning a Copilot license has no effect on a user's administrative permissions.
