Who coordinates the sequencing of events within the central processor of a computer?

The correct answer is D. Control unit.

The control unit is the part of a computer that coordinates the sequencing of operations. It fetches instructions from memory, decodes them, and then sends the appropriate signals to the other parts of the computer to carry out the instructions.

The logic unit is responsible for performing logical operations, such as AND, OR, and NOT. The arithmetic unit is responsible for performing arithmetic operations, such as addition, subtraction, multiplication, and division. Registers are temporary storage locations for data and instructions.

None of the other options are correct because they are not responsible for coordinating the sequencing of events within the central processor of a computer.
