To determine the control signals of MOSI (Master Out Slave In), we need to analyze the options provided. MOSI is typically used in communication protocols, such as SPI (Serial Peripheral Interface), where it helps in transmitting data from the master device to the slave device.

### Control Signals Analysis
1. **SIMO (Single Input Multiple Output)** - This describes a configuration where a single input can serve multiple outputs. While it relates to the general wiring of signals, it doesn’t specifically identify the control signals associated with MOSI.

2. **MTSR** - This might refer to a specific signal in some contexts but is not widely recognized as a standard control signal for MOSI.

3. **SOMI (Slave Out Master In)** - This is typically the opposite of MOSI. It refers to the data sent from the slave back to the master.

4. **MRST (Master Reset)** - This is commonly a reset signal but not directly related to data transfer by MOSI.

5. **SDI (Slave Data In)** - This typically refers to the data going into the slave, similar to MOSI, but not a direct control signal.

6. **DI (Data In)** - This could refer specifically to data coming in but is not typically a label used for MOSI.

7. **DIN (Data Input)** - This is often another term for input data but again not a standard signal identifying MOSI.

### Conclusion
MOSI is a main data output line from the master for SPI communications, so while SIMO relates generally, it might not be precise. Given the lack of precise standard terminology and context for some of these terms, the answer most likely indicating control signals of MOSI would be "Both a and b" (assuming "a" refers to SIMO and "b" is MTSR based on the general configurations).

### Final Answer
**Both a and b.**
