Which one of the following stores the results produced by arithmetic and logic unit of a computer ?

The Accumulator (ACC) is a general-purpose register used as a temporary storage location for the intermediate and final results produced by the Arithmetic Logic Unit (ALU). In most computer architectures, when the ALU performs an operation like addition or logical comparison, the output is directly stored in the accumulator for further processing or transfer to memory.

• Instruction Register (IR): Stores the instruction currently being decoded or executed by the CPU.
• Program Counter (PC): Contains the memory address of the next instruction to be fetched and executed.
• Memory Address Register (MAR): Holds the memory address from which data will be fetched to the CPU, or the address to which data will be sent and stored.
