Option 1 states that a secular state refuses theocracy. Theocracy refers to a system where religious leaders have authority over the government. This character aligns with the idea of a secular state, as it implies that the government should not be governed by religious principles.

Option 2 argues that a secular state separates religion from the state. This means that the government does not have an official religion and does not favor any particular religious group. This character is commonly associated with the concept of secularism, as it ensures that the government does not interfere with or favor any specific religion.

Option 3, which the correct answer states is NOT a character of a secular state, suggests that a secular state must be democratic. While it is true that many secular states are also democratic, it is not a requirement for a state to be considered secular. A secular state primarily focuses on the separation between religion and the government, without necessarily implying a specific form of governance.

Option 4 suggests that a secular state must prevent religious conflict and promote religious harmony. Although promoting religious harmony is often an objective of a secular state, it is not a foundational characteristic. Ensuring religious freedom and the neutrality of the government towards religion is the primary goal of a secular state.

Overall, the provided answer is correct
