The correct answer is B. using a custom agent that is grounded in work data . Microsoft Learn states that agents that access shared tenant data , such as SharePoint or Graph Connector content, are billed based on metered consumption . Microsoft also describes pay-as-you-go for Microsoft 365 as applying to agents in Microsoft 365 Copilot Chat , where organizations pay only for the messages used instead of assigning a full Microsoft 365 Copilot license. That is exactly the scenario described in option B: a custom agent grounded in work data. The other options are not the intended pay-as-you-go scenario. A Teams meeting recap and Copilot in Word are standard Microsoft 365 Copilot application experiences tied to licensed Copilot functionality, not metered agent consumption. Researcher is an advanced Microsoft 365 Copilot agent available as part of Microsoft 365 Copilot capabilities, not the documented example of pay-as-you-go replacing a Copilot license. Microsoft' s pay-as-you-go guidance centers on agent-based usage , especially agents grounded in organizational work data.
