Which of the following describe "secularism"?

opposition to religious chauvinism

The correct answer is Option (2) → opposition to religious chauvinism

"The Indian meanings of secular and secularism include the western sense but also involve others. The most common use of secular in everyday language is as the opposite of communal. So, a secular person or state is one that does not favour any particular religion over others. Secularism in this sense is the opposite of religious chauvinism and it need not necessarily imply hostility to religion as such. In terms of the state-religion relationship, this sense of secularism implies equal respect for all religions, rather than separation or distancing. For example, the secular Indian state declares public holidays to mark the festivals of all religions.".
