The correct answer is: A. host operating system
The host operating system is the operating system that runs on the physical hardware. It provides a platform for other software to run on, and it manages the resources of the computer, such as the CPU, memory, and storage.
The software layer is made up of applications that run on the host operating system. These applications can be anything from word processors to games to web browsers.
The VM layer is made up of virtual machines. A virtual machine is a software program that creates a simulated computer environment. It can run its own operating system and applications, just like a physical computer.
Therefore, the host operating system should be placed in the second lowermost layer.
