The correct answer is Option (4) → secularism

Secularism does not pose a challenge to the diversity of India; rather, it supports and upholds the country's pluralistic nature. Secularism promotes the idea that the state treats all religions equally and does not favor or discriminate against any religion. In contrast, communalism, regionalism, and casteism can create divisions and conflicts within society, challenging the unity and diversity that secularism seeks to maintain.
