Explanation:

Isolationism means staying out of foreign - affairs and alliances. Avoiding alliances with other nations is a key aspect of isolationist policy. Forbidding Americans to travel overseas is extreme and not typical of 1930s isolationism. Building up armed forces is more about national defense than isolationism. Favoring one nation over another goes against the idea of isolation.

C. avoiding alliances with other nations
