The correct answer is D) are resistant to change.
Stereotypical beliefs are resistant to change.
The problem with stereotypes is that they are not based on truth but in external perceptions that have been passed through time and generations. Stereotypes are commonly generalized and simplified notions about people, a group in society, a race, or ethnicity. So in using stereotypes, people are prejudging other people, countries, or events, without knowing the truth. So we have to avoid stereotypes and allow us to know others or inform about how things are in other places, to not appear ignorant through stereotypes.
