Ethnocentrism is defined as:

Ethnocentrism refers to the perspective that one's own nation or ethnic group is superior to others. This belief often leads individuals or groups to evaluate other cultures through the lens of their own, resulting in a biased and potentially negative view of those cultures. The emphasis here is on the perceived superiority, which can foster nationalism, prejudice, and discrimination against individuals from differing backgrounds.

When considering the options, the contextual distinction becomes clear. While the first choice focuses on economic status, which does not inherently relate to cultural or ethnic superiority, the third option mentions the importance of cultural traditions, reflecting a form of cultural pride rather than supremacy. The fourth choice centers on ignorance; however, ethnocentrism is more about an active belief in superiority than a passive lack of understanding. Therefore, the correct answer emphasizes the central tenet of ethnocentrism: the belief that one's own nation or ethnic group holds a higher status compared to others.
