___________ enrollment enables large scale over the air bulk Android (8.0+) deployments across multiple device makers so organizations can mobilize their employees with ease and no manual setup.

Zero-touch enrollment is the correct answer because it is specifically designed for large-scale, over-the-air bulk deployments of Android devices (8.0+). It allows organizations to pre-configure devices so they are automatically provisioned with the necessary EMM policies and applications upon first boot, without manual setup. NFC and QR code enrollment are suitable for smaller-scale deployments or individual device setup, as they require physical interaction with each device. EMM token enrollment is a method for users to manually enroll a device into an EMM, which is not a bulk, zero-touch solution.
