During the ____________ process, each bootstage cryptographically verifies the integrity and authenticity of the next stage before executing it.

Verified Boot is the correct answer because it's a security process in Android that ensures the integrity of the device's software from the moment it starts up. Each stage of the boot process (e.g., bootloader, kernel, system partition) cryptographically verifies the next stage before execution. If any stage is tampered with, Verified Boot can prevent the device from booting or alert the user, protecting against malware and unauthorized modifications. Kernel checking is too narrow; Verified Boot encompasses more than just the kernel. Hashtagging is irrelevant to device security. System check is a general term and doesn't specifically describe this cryptographic verification process.
