Answer options

Correct answer: B

Explanation

The correct answer, B, highlights that a virtual machine operates in a fully isolated environment, separate from the host OS.

Option C is wrong since virtual machines are typically more heavyweight than containers, and option D is inaccurate as it describes containers, which share the host OS kernel.
