Options

• Waterways

• Airways

• Railways

Answer 1

The cheapest mode of transport is waterways.

Explanation:

Waterways are the cheapest mode of transport because they use natural waterways (rivers, seas, and canals), which don't need to be built or maintained like roads or railroads. Waterways are the least expensive kind of transportation. Water's buoyancy also makes it possible to move heavy items with less energy.
