Answer is Right!
Answer is Wrong!
The correct answer is C. 6 km/h.
Shunting is the movement of railway vehicles within a yard or depot. It is usually done at low speed, typically 2-10 km/h. The impact speed of shunting of one box wagon is typically 6 km/h.
Option A is incorrect because it is too low. Option B is incorrect because it is too high. Option D is incorrect because it is not a realistic speed for shunting.
