Which best exemplifies the caste system?

The Caste System, primarily associated with India, exemplifies a hierarchical social structure where individuals are born into specific groups, or "castes," that determine their social status, occupation, and marital prospects. At the top are the Brahmins (priests and scholars), followed by Kshatriyas (warriors and rulers), Vaishyas (merchants and landowners), and Shudras (laborers and service providers). Below these four main categories are the Dalits, formerly referred to as "Untouchables," who face social ostracism and discrimination. This rigid system has historically influenced social interactions, economic opportunities, and cultural practices.
