The correct answer to this open question is the following.
Although there are no options attached we can say the following.
A policy of remaining apart from the affairs or interests of other groups, especially the political affairs of other countries is called "Isolationism."
When a country decides to not act or intervene in the affairs of other nations, it is said that it maintains a foreign policy of neutrality due to its isolitianism practice.
An example of Isolationism is when the United States decided to remain neutral through most of WW1. and World War II.
During the beginning of World War I, United States President, Woodrow Wilson, decided to maintain the foreign policy of neutrality and do not involve the United States in the European issues.
Something similar happened with US President Franklin D.Roosevelt in the first stages of World War II. Different events forced both presidents to ask Congress for a declaration of war against Germany.
