The correct answer is A. It greatly reduced the time required for ships traveling from the eastern to the western United States
Step-by-step explanation:
The Panama Canal is a man-made structure located in Panama that connects the Pacific and the Caribbean Ocean, because of this the canal is used for maritime trade as it reduces the time for ships to cross from the east of America to the West. Additionally, the construction of the Canal took several years and was supported by different companies and countries as the project was started by France in 1881, but in 1904 the project was taken by the U.S. Besides this, the construction and the expansions planned for the future have been criticized due to the impact they have on environment as this zone is the habitat of multiple animal and plants species.
Therefore, the statement that is true about the Panama Canal is " It greatly reduced the time required for ships traveling from the eastern to the western United States" because the construction of the Canal implied ships could cross from one side to the other in a short time, rather than surrounding all the continent.
