The responsibility of citizens towards nation-building is to

Step 1: Analyze the question The question asks about a citizen's responsibility toward nation-building. Nation-building means helping a country grow, stay united, and develop politically, socially, and economically. So we need the option that describes a positive, constructive duty.

Step 2: Explain the concept Citizens have rights, but they also have civic duties. These include:

• Obeying the laws
• Paying taxes
• Voting and taking part in elections
• Participating in community and national development
• Contributing to governance through dialogue and civic engagement
• Protecting public property

Nation-building depends on active, peaceful, and responsible participation.

Step 3: Evaluate each option

• A. Encourage civil disobedience in the face of hardship: Civil disobedience means deliberately refusing to obey laws. It disrupts order and does not build the nation. Wrong.
• B. Participate and contribute to decision making: This is a constructive civic duty. Through voting, public debates, and giving feedback on policies, citizens help shape the nation's direction. Correct.
• C. Stampede government policies and programmes: "Stampede" means to rush in a disorderly way or disrupt. It works against development. Wrong.
• D. Boycott and withdraw services to the state: This weakens the state and hurts development. Wrong.

Step 4: Answer The correct answer is B.

Tip: In Government and Civic Education questions about "responsibility" or "duty" of citizens, choose the option that is positive, lawful, and constructive (participating, obeying laws, paying taxes, voting). Eliminate options with words like disobedience, boycott, disrupt, withdraw.
