This is a very oddly worded question. However, based on my knowledge on computers (as I have built one), I believe the correct answer is:
A- Software and hardware.
Computers are an operating system made up of the CPU, GPU, Ram, storage, motherboard, etc. On the other hand, in order to be able to use a computer properly, you have to buy a operating system, such as windows 7, or windows 10 (recent and most used operating system). Sorry if I get this wrong, but if I helped you, please mark as brainliest!
