B
Correct answer
Explanation
The system unit (also called the computer case or tower) is the container or enclosure that houses the main electronic components of a computer, including the motherboard, processor, memory, and power supply. It coordinates and connects all the internal hardware but doesn't directly control input/output devices, manipulate data (that's the CPU's job), or perform arithmetic operations (also the CPU). Note: There's a typo in option B where 'contain' should read 'container.'
