All the given options can be used to maintain the head pressure of a system with an air-cooled condenser. 
- Fan cycling can be used to adjust the airflow across the condenser and maintain the head pressure within the desired range.
- Condenser flooding involves adding more refrigerant into the system to increase the condenser's heat rejection capacity, which helps to maintain the head pressure.
- Dampers can be used to control the outdoor airflow across the condenser coil, which helps to maintain the head pressure. 
Therefore, all three options are viable solutions for maintaining head pressure and choosing all of the above is the best answer.
