Ethnocentrism is not one of the basic components of culture.
Ethnocentrism refers to the way to look at the world basically from the point of view of one's own culture. Culture refers to the arts and social beliefs which are followed by a social group. It has certain basic components:
Values: Values in the culture are the standards which decide what is wrong and what is right.
Symbols: A symbol refers to some object, word, or an action that represents something that is culturally defined.
Language: It refers to the way people communicate with one another. The accent and the style is defined by the cultural background.
Hence, the option which is not a basic component of culture is ethnocentrism.
