Option C is the correct answer because it comprehensively addresses both security requirements. Shielded VM with secure boot, vTPM, and integrity monitoring protects against boot-level and kernel-level malware by ensuring the integrity of the boot process and monitoring for unauthorized changes. Confidential Computing provides hardware-based encryption for data in use, preventing the underlying host system from accessing VM memory contents. Enforcing these through organization policies ensures consistent application across all workloads. Option A lacks Confidential Computing for data in use protection. Option B focuses only on threat detection without the foundational protections. Option D uses hardened images but doesn't include Shielded VM's specific boot and kernel protection features.
