Solution

The correct option is B Address bus

A physical connection between the microprocessor memory other parts of the microcomputer is known as Address bus.

Address Bus: It is a group of wires or lines that are used to transfer the addresses of Memory or I/O devices. It is unidirectional.In Intel 8085 microprocessor, Address bus was of 16 bits. ... Data Bus:As name tells that it is used to transfer data within Microprocessor and Memory/Input or Output devices.

Address Bus. The address bus carries the address of the piece of memory or I/O device to be read from or written to. It is a unidirectional bus, which is to say that data travels only one way; from the CPU to memory. The number of lines on the bus determines the number of addressable memory elements.

When a processor or DMA-enabled device needs to read or write to a memory location, it specifies that memory location on the address bus (the value to be read or written is sent on the data bus). The width of the address bus determines the amount of memory a system can address.
