Solution

The address of the next instruction to be executed is provided by the Program Counter.

Here's a step-by-step explanation:

  1. The Program Counter (PC) is a type of register in a computer processor that holds the address (location) of the instruction in memory that the computer's central processing unit (CPU) should execute next.

  2. When a program is running, the CPU fetches the instruction from memory that the PC points to.

  3. After an instruction is fetched, the PC is updated to point to the next instruction. This could be the next sequential instruction in memory, or an instruction in a different location if a branch or jump instruction was executed.

  4. Therefore, the PC always points to (provides the address of) the next instruction to be executed.

So, the correct answer is B. Program Counter.
