Question

Quizplus · Accepted Answer

Railroads are the most efficient form of transportation for bulk items like coal, grains, nonmetallic minerals, and lumber products. They can handle large quantities at once, have lower transportation costs per unit, and are more environmentally friendly than other forms of transport. Water carriers (option D) can also be efficient but may not be available in all regions and may have limited access to inland areas. Air cargo (option A) and motor freight (option B) are generally more expensive and less efficient for bulk items compared to railroads.
