B Correct answer
Explanation

Steam engines typically have a weight-to-power ratio of 60-80 kg per HP, which is much higher than modern diesel or electric locomotives. Values like 10-15 kg/HP (option A) are more typical of modern locomotives, while 20-30 kg/HP (option C) is still too low for steam technology. 100-150 kg/HP (option D) would be extremely heavy even for steam.
