Correct Option: C. Discouraging inter-religious marriages Explanation of the Correct Answer: The question asks for the step that does not contribute to sustaining national unity. Among the options provided, option C, "discouraging inter-religious marriages," is the correct answer because it promotes division rather than unity.

1. Understanding National Unity: National unity refers to the sense of togetherness and solidarity among the citizens of a nation, regardless of their diverse backgrounds, including ethnicity, religion, and culture. It is essential for social stability, peace, and progress.
2. Impact of Inter-Religious Marriages: Inter-religious marriages can serve as a bridge between different communities, fostering understanding, tolerance, and acceptance. By encouraging these unions, societies can break down barriers and promote a culture of inclusivity. Discouraging such marriages, on the other hand, can lead to segregation, discrimination, and conflict among different religious groups, which undermines national unity.

Explanation of Why Other Options Are Incorrect or Weaker:

• Option A: Emphasis on factors that unite a nation This option is correct and contributes positively to national unity. By focusing on shared values, common goals, and collective identity, citizens can strengthen their bonds and work together towards a harmonious society. Emphasizing unity helps to mitigate divisions based on differences.
• Option B: Respecting the national symbols This option is also correct and plays a crucial role in fostering national unity. National symbols, such as flags, anthems, and emblems, represent the identity and values of a nation. Respecting these symbols helps to instill pride and a sense of belonging among citizens, reinforcing their commitment to the nation.
• Option D: Working towards achieving national objectives This option is correct as well. When citizens and leaders work together to achieve common national objectives, it creates a sense of purpose and collaboration. This collective effort can enhance social cohesion and promote a shared vision for the future, which is vital for sustaining national unity.

• National unity is essential for social stability and progress.
• Inter-religious marriages promote understanding and inclusivity, while discouraging them fosters division.
• Emphasizing unifying factors, respecting national symbols, and working towards common objectives are all positive steps towards sustaining national unity.

By understanding these concepts, students can better appreciate the importance of fostering unity in diverse societies and the detrimental effects of actions that promote division.
