The correct answer is: C. Sr. DSTE
The Sr. DSTE (Senior Divisional Signal and Telecommunication Engineer) is responsible for preparing the station working rules of an interlocked station. The station working rules are a set of instructions that govern the safe operation of the station. They include information on the layout of the station, the location of switches and signals, and the procedures for operating the station.
The DOM (Divisional Operating Manager) is responsible for the overall operation of the division. The COM (Chief Operating Manager) is responsible for the overall operation of the company.
The Sr. DSTE is a more senior position than the DOM or COM. The Sr. DSTE has a more specialized knowledge of signal and telecommunication engineering, which is necessary for preparing the station working rules.
The station working rules are a critical document for the safe operation of an interlocked station. They must be prepared by a qualified engineer with the appropriate knowledge and experience.
