what was america's response about joining the league of nations (after ww1)?

Question

a- the public thought that america should lead the league of nations
b- the public generally supported the idea but wanted to play a smaller role
c- it supported the president and actively took part in the league of nations
d- it believed that the united states should stay out of european affairs

im thinking its c because at the time wilson was president at the time and he was the one who had the goal of creating the league of nations but im not too sure.
