A user wants to purchase a CAD application that requires 8GB of RAM to operate. Which of the following operating system types is required?
The correct answer is D. 64-bit. To utilize 8GB of RAM, an operating system must be 64-bit, as 32-bit systems have a much lower memory addressable limit.

Why each option
To utilize 8GB of RAM, an operating system must be 64-bit, as 32-bit systems have a much lower memory addressable limit.
8-bit operating systems are extremely archaic and can only address very small amounts of memory, far less than 8GB.
16-bit operating systems are also outdated and cannot support the large memory requirements like 8GB of RAM.
32-bit operating systems have a maximum theoretical RAM limit of 4GB (2^32 bytes), making them incapable of utilizing 8GB of RAM.
A 64-bit operating system is required because 32-bit operating systems can typically only address up to 4GB of RAM (specifically, 2^32 bytes or 4,294,967,296 bytes). To access and utilize 8GB of RAM, an OS must be built on a 64-bit architecture, which supports significantly larger memory address spaces.
