In case of vehicles escaping on wrong line, ________ bell code is given on block Instrument to inform the station in advance. A. 000000-0000 B. 00000-0 C. 0000-000 D. 0000-0000

The correct answer is: A. 000000-0000.

The bell code 000000-0000 is given on block Instrument to inform the station in advance in case of vehicles escaping on wrong line. This code is used to alert the station that a vehicle is on the wrong line and that they need to take action to prevent a collision.

The other options are incorrect because they do not correspond to the correct bell code for this situation. Option B, 00000-0, is the bell code for a train approaching a station. Option C, 0000-000, is the bell code for a train departing from a station. Option D, 0000-0000, is the bell code for a train passing a signal at danger.

I hope this helps!
