Which of the following best describes the concept of racial categories in sociology?

In sociology, racial categories refer to the way people are grouped based on shared physical characteristics, like skin color, facial features, and hair type. These categories are not just about biology; they also involve social and cultural meanings that society attaches to these differences. For example, someone might be classified as "Black" or "White," but these labels can carry different implications depending on the historical and social context. This means that racial categories can influence people's experiences, opportunities, and how they are treated in society. Understanding these categories helps us see how race impacts social interactions and inequalities.
