Which most accurately describes Hinduism's impact on Indian society and culture?

The best option of the answer choices provided is Option 4. Hinduism established a rigid cast system, but it was formally abolished in the mid 20th century.

Explanation:

There are four main categories in the Hindu caste system - Shudras, Vaishyas, Kshatriyas, and Brahmins. The Hindu God of creation called Brahma was said to have created the groups. One of the most important Hindu texts, Manusmriti, dates to 1000 years before Christ, and it says that the caste system is the framework for order and regularity in Hindu society. Discrimination on the basis of caste was banned by law in 1948 in India, although unfortunately there is continued stigma and discriminatory practices to this day.
