When VP vehicles are attached in a goods train the maximum number of VPvehicle in one group is A. 10 B. 6 C. 8 D. None of these

The correct answer is: B. 6

VP vehicles are attached in a goods train in groups of 6. This is because the maximum number of VP vehicles that can be attached to a goods train is 6. If more than 6 VP vehicles are attached to a goods train, the train will be too heavy and will not be able to travel safely.

Option A is incorrect because 10 is not the maximum number of VP vehicles that can be attached to a goods train.

Option C is incorrect because 8 is not the maximum number of VP vehicles that can be attached to a goods train.

Option D is incorrect because none of the other options are correct.
