Both George Washington and Thomas Jefferson remained quite apart from the situation of chaos and violence in France in the last decade of the nineteenth century.
When in 1793, the French diplomat Genet promoted actions to determine the support of the United States to France in its War against Great Britain, both opposed him to meddle in internal affairs and sent him back to his country.
Washington pushed Jay's treaty in 1794 to normalize trade relations with England. Jefferson disagreed because he had a penchant for supporting France but when he was defeated in the Parliament vote he accepted Washington's policy.
I believe the answer is C, immunity because (immunity) means protection or exemption from somethings, especially an obligation or penalty. So the key word in the question is protection. I hope this helps and just stating I am NOT 100% sure.
