The correct answer is **mDecode**.

### Explanation
In microprogramming, a microinstruction is a low-level instruction that provides direct control over the hardware components of a computer system. The **mDecode** microinstruction specifically refers to a stage where the microcontroller unit (μCU) populates the decode registers. During this cycle, the μCU interprets the instruction fetched into the instruction register (IR) and translates it into control signals that will initiate the necessary operations.

The other options:
- **mLoadIR** is related to loading the instruction register with a new instruction.
- **mLoad** typically refers to the loading of data into registers or memory.
- **mb** does not correspond to any standard term in this context.

Thus, the **mDecode** operation is essential for understanding and executing the instruction correctly, ensuring that the system waits for one complete cycle to process the information before moving forward.
