D. to ensure that Americans could use the Mississippi River and access the port of New Orleans
Explanation:
The main reason that President Thomas Jefferson sent representatives to France is to "ensure that Americans could use the Mississippi River and access the port of New Orleans."
Mississippi River and New Orleans port was essential to the United States trading routes, as it is the area in which they make export and import operations. Hence, Thomas Jefferson believed they need to control the area to be more successful in the importation and exploitation of the business, therefore the need to send a representative to France to make a deal on the Louisiana Purchase.
President Wilson asked the Congress to arm the American merchant ships because of the dangers that lay ahead. He wanted to safeguard the ship from any imminent attack. He also wanted to protect America no matter the cost.
