The control register holds instructions or control information before it is sent to the decoder in the CPU.
Data register → holds data being transferred to/from memory or I/O.
Accumulator → used by the ALU to store intermediate results.
Address register → holds memory addresses.

So, the Correct answer: Control register.

Memory data register (MDR) : is a register used for holding information that is in the process of being transferred from the RAM to CPU or vice versa.
