Answer & Explanation
The correct answer is Option D: 2.
As per SOLAS and FSS Code requirements for fixed CO2 systems, if pilot cylinders are used to release the CO2 from the main storage cylinders, a minimum of two pilot cylinders are mandatory. This ensures critical operational redundancy and system reliability, preventing a single point of failure.
