The correct answer is letter B

Nationalism is an ideology that arose in the 19th century when the nation-states in Europe were affirmed.

The term is used to describe the feeling and attitude that members of a nation have when forming national identity.

Nationalism comes after Napoleon conquered much of Europe. Against the resistance to the French general, the idea arises to strengthen the characteristics of each country in order to differentiate themselves from the invader.
