To view the number and type of ChromeOS upgrades purchased and in use, administrators should check the
"Subscriptions" section in the billing area of the Google Admin console. This section provides a clear overview of the organization's ChromeOS upgrade subscriptions and usage.
Other options are incorrect because they don't directly provide information about ChromeOS upgrade subscriptions:
* Option A (Verify upgrades on devices page): Shows upgrades on individual devices, not the overall purchase and usage.
* Option C (Contact partner to verify): Unnecessary if the information is readily available in the Admin console.
* Option D (Check reports page for upgrades): Might provide some usage data, but not the purchase details.
