Assertion (A): Stereotypes do not recognize the variation across individuals and across contexts or across time.
This statement is true. Stereotypes are oversimplified and generalized beliefs or ideas about a particular group of people. They often ignore the diversity within the group, treating all individuals within the group as if they are the same. Stereotypes tend to overlook variations across individuals, contexts, or changes over time.
Reason (R): They treat an entire community as a single whole.
This reason is correct and provides the explanation for the assertion. Stereotypes involve treating an entire community or group as a single, homogenous entity, disregarding individual differences or variations within the community. The reason aligns with the assertion by emphasizing that stereotypes often fail to recognize the diversity and nuances present within a group.
