Which statement describes a virtual machine's characteristic?

A virtual machine (VM) runs a full-fledged guest operating system on top of a hypervisor, which in turn runs on the host hardware. This architecture provides complete isolation from the host OS and other VMs, as each VM has its own kernel, libraries, and binaries. This isolation is a key security and stability benefit. Containers, while also providing isolation, share the host OS kernel, binaries, and libraries, making them more lightweight and resource-efficient than VMs. However, this shared kernel means they are not as completely isolated as VMs. Therefore, the statements claiming VMs are more resource-efficient or lightweight than containers, or that they share the host OS kernel, are incorrect.
