Answer is Right!
Answer is Wrong!
The correct answer is D. 0000-00.
In case of train parting, the bell code given on block instrument is 0000-00. This means that the train has parted from the previous station and is now on its own. The bell code is used to alert the next station that the train is coming and to ensure that the track is clear.
The other options are incorrect because they do not correspond to the correct bell code for train parting. Option A, 00000-0, is the bell code for a train arriving at a station. Option B, 000000-0, is the bell code for a train departing from a station. Option C, 000000-000, is the bell code for a train passing a signal at danger. Option D, 0000-00, is the correct bell code for train parting.
