The correct answer is: Only argument II is strong.
Argument I is not strong because it is based on the assumption that reservation of seats and posts on communal basis will check most of the inter-communal biases. However, there is no evidence to support this assumption. In fact, some studies have shown that reservation can actually lead to increased inter-communal tensions.
Argument II is strong because it is based on the principle of secularism. Secularism is the principle of separation of
religion and state. In a secular state, the government should not favor any particular religion or religious group. Reservation of seats and posts on communal basis would violate this principle.Therefore, only argument II is strong.
