The operating system creates … from the physical computer a. Virtual space b. Virtual computer c. Virtual device d. None

The answer will be b. Virtual computer

its creates an virtual environment ,with the help of OS we can access hardware(internal,external or even virtual),i am sure all us aware of what is internal and external what does virtual hardware. its hides the physical characteristics of a computing platform from users, instead showing another abstract computing platform.At its origins, the software that controlled actualization was called a "control program", but the terms "hyper-visor" or "virtual machine monitor" are now preferred.

please correct me if its incorrect.

Thanks.
