The correct answer is: C. 0-00-00
ACP stands for Automatic Coach Protection. It is a safety system that is used in trains to prevent derailments. The system works by monitoring the train’s speed and position, and if it detects that the train is going too fast or is off the track, it will automatically apply the brakes.
In case of ACP, the Guard of EMU shall give 0-00-00 bell. This means that the train is going too fast and the Guard needs to slow down the train. The Guard will do this by applying the brakes.
The other options are incorrect because they do not correspond to the correct bell code for ACP.
Option A: 00-00-00 is the bell code for “Train is on the right track.”
Option B: 00-0-00 is the bell code for “Train is on the left track.”
Option D: 000-0-00 is the bell code for “Train is stopped.”
