Answer:

If we analyze the given piece of code, C1, C2, C3 and C4 are 4 classes. 

C1 is the base class and does not derive from any other class.

C2 is a class which inherits C1.

C3 is a class which inherits C2 and indirectly inherits from C1.

C4 is a class which inherits C1 directly. If analyses the instance creation statement,

c1 instance of C1 is valid because the object is created for class C1.

c1 c2 = new C2() is valid once again the object is created for Class C2

c1 c3 = new C3() is invalid because the class C3 directly inherits from C2 and not from C1

c1 c4 = new C4() is valid

Where must virtualization be enabled for VM (virtual machine) software to work?

Lelu [443]

Answer:

b) BIOS/UEFI

Explanation:

Virtualization can be defined as a technique used for the creation of a virtual platform such as a storage device, operating system, server, desktop, infrastructure or computing resources so as to enable the sharing of resources among multiple end users. Virtualization is usually implemented on a computer which is referred to as the "host" machine.

Generally, virtualization must be enabled in the BIOS/UEFI for VM (virtual machine) software to work.

BIOS is an acronym for Basic Input/Output System while UEFI is an acronym for Unified Extensible Firmware Interface. BIOS/UEFI are low-level software that serves as an intermediary between the operating systems and the computer's firmware or hardware components. The UEFI is actually an improvement of the BIOS and as such is a modernized software.

Basically, the BIOS/UEFI is a software which is an essential tool or feature which must be enabled to link the virtual machine with the hardware components of the computer.
