To understand the evolution of racial categories, we start with D, where the term 'Caucasian' was first used as a geographical reference to the Caucus Mountains. Next, we see B, where racial classifications began to be viewed through a biological lens, suggesting that people were categorized based on physical traits. Following this, A shows that the term 'Caucasian' expanded to include various ethnic groups from Europe to India, reflecting a broader understanding of race. Finally, C illustrates how concepts of race became increasingly influenced by social and political contexts, highlighting that race is not just about biology but also shaped by society and power dynamics. This progression shows how our understanding of race has developed over time, from geographical origins to complex social constructs.
