The correct answer is: None of these.
Hand shunting speed is the speed at which a train is moved by hand. It is typically much slower than the speed of a train that is being moved by a locomotive. The exact speed of hand shunting will vary depending on the type of train, the weight of the train, and the conditions of the track.
Option A, 5 kmph, is too slow for most types of trains. Option B, 10 kmph, is a more realistic speed for hand shunting. However, it is important to note that the speed of hand shunting will vary depending on the factors mentioned above. Option C, 8 kmph, is an intermediate speed between 5 kmph and 10 kmph. However, it is not a specific speed that is used for hand shunting. Option D, None of these, is the correct answer because it is the only option that does not specify a specific speed for hand shunting.
