Explanation

Docker uses OS-level virtualization (containerization), meaning containers share the host operating system's kernel, making them lightweight and fast. A bare metal (Type 1) hypervisor, such as VMware ESXi or Microsoft Hyper-V, runs directly on the physical hardware independent of any host OS and creates full virtual machines with their own separate OS instances. Docker does not boot full OS instances (A), typically uses fewer resources than hypervisors (B), and is not specifically optimized for legacy systems (C).
