Answer:
Option D.
Explanation:
A covered wagon, is the right answer.
In pre-industrial America, the "Prairie Schooner' was a dominant form of transportation. The Prairie Schooner was used by the Americans to travel to the west. Its name was derived from white canvas cover wagon or bonnet which presented its appearance as a sailing ship (schooner) from distance. It was often associated with the Conestoga wagon, which was more popular in the eastern U.S. However, Prairie Schooner was lighter and smaller than the Conestoga wagon. In short, it was a covered wagon used to travel to the west.
