I think that you just answered your own question in the question you asked.
The correct answer is C) he did not want to put the United States further into depth.
Jefferson's main concern regarding the Louisiana purchase was that he did not want to put the United States further into depth.
Jefferson was decided to buy the Louisiana territory and sent James Madison to France to help Robert Livingstone -Minister to France- with the negotiations. The result was a successful one. The United States accepted to pay $11,2500,000 for 828,000 square miles of the Louisiana territory. The agreement was signed on May 2, 1803.
Each country had a different economic system (capitalism in the USA and communism in the SU), which caused competition.
This competition led to military competition and a nuclear arms race, which was called the Cold War. The nuclear arms race became the greatest point of tension.
