A Correct answer
Explanation

Interlocking is a safety system that prevents conflicting movements by ensuring signals and points (switches) cannot be set to dangerous combinations. While C.T.C (Centralized Traffic Control), A.T.C (Automatic Train Control), and pilot guard systems are safety measures, interlocking is fundamental and directly prevents accidents by mechanical/electrical logic that makes unsafe operations impossible. The other options are more advanced systems but interlocking is the most direct answer.
