How many minimum BP pressure is require in engine to charge Goods train? A. 4.8 kg/cm2 B. 6.00 kg/cm2 C. 5.8 kg/cm2 D. 5.00 kg/cm2

The correct answer is: A. 4.8 kg/cm2

The minimum boiler pressure required to charge a goods train is 4.8 kg/cm2. This is the minimum pressure required to ensure that the train has enough power to move and to prevent the boiler from overheating.

Option B, 6.00 kg/cm2, is too high and would not be necessary for a goods train. Option C, 5.8 kg/cm2, is close to the minimum required pressure, but it is not necessary to go above the minimum. Option D, 5.00 kg/cm2, is too low and would not be sufficient to power a goods train.
