All the above are characteristics of caste:

1. Ascribed: Caste is typically ascribed at birth, meaning individuals inherit their caste status from their parents, and it is not based on personal achievements or choices.

2. Endogamous: Caste often involves the practice of endogamy, where individuals marry within their own caste, maintaining social and cultural boundaries.

3. Linked to an occupation: Traditionally, many caste systems are associated with specific occupations or professions, and individuals are expected to follow the occupation traditionally associated with their caste.
