D) Container ships

Explanation:

The waterways are by far the best way of transporting any type of goods worldwide. The cargo ships or the so called Container ships are large and can take many large containers across the sea. This is great because almost every country in the world that has a coast also has a port, thus it is quite simple for any product to arrive much faster to the wanted destination.
