The question asks: What part of the computer carries out arithmetic operations, such as addition, subtraction, multiplication and division?

First, note that the provided data does not include any answer options to analyze. Without the list of choices, we cannot assess each alternative for accuracy or misconceptions.

Nevertheless, we can reason about the core concept: the component responsible for performing arithmetic operations in a computer is the central processing unit (CPU). The CPU contains the arithmetic logic unit (ALU), which executes basic arithmetic and logical operations. When a program requires calculations, the CPU fetches the instructions, decodes them, and uses the ALU to perform the actual arithmetic, then stores the results back in memory or registers.

If additional options had been provided, we would compare them to this understanding:
- If an option names the CPU or its subcomponent ALU as the entity performing arithmetic, that would be correct.
- If an option mentions memory, storage, or input/output devices (I/O) as handling arithmetic, those would be incorrect, because those components serve other roles (holding data, persisting information, or interfacing with peripherals) and do not perform computations.
- If an option suggests that arithmetic is handled entirely by software without dedicated hardware support, that would be misleading; while software can guide computations, the actual arithmetic operations are carried out by the CPU/ALU hardware.

In summary, given the standard understanding of computer architecture, the CPU (specifically the ALU within the CPU) is the component responsible for carrying out arithmetic operations. If you provide the missing answer options, I can map each one to this reasoning and explain why each is correct or incorrect.
