You have to solve on the basis of MODE OF TRANSPORT not MEANS OF TRANSPORT SOF you yourself have given mode of transport is basis but you gave wrong answer! correct answer is A as means of transport includes transport which carry goods, passengers etc. And mode of transport means land, air or water transport. All the options are land transport but train runs on rail and other vehicles(auto rickshaw, truck and bus) run on road So answer is A
