The application of the common principles that are important to improve decision-making processes and…

Step 1: Analyze the question The question asks for the term that describes applying common principles (such as accountability, transparency, rule of law, participation and responsiveness) to improve decision-making, strengthen democracy, and boost social and economic development.

Step 2: Explain the concept Good governance is the exercise of political, economic and administrative authority guided by key principles:

• Accountability
• Transparency
• Rule of law
• Participation of citizens
• Responsiveness to people's needs
• Equity and inclusiveness
• Effectiveness and efficiency

When leaders apply these principles, decisions are better, democracy is strengthened, and social and economic development improves.

Step 3: Check each option

• A. Fundamental human rights: These are the basic rights guaranteed to every citizen (life, liberty, expression). They are only one component of good governance, not the application of decision-making principles.
• B. Good governance: It matches the definition exactly: common principles applied to improve decision-making, democracy and development.
• C. Separation of powers: This is the division of government into the executive, legislature and judiciary to prevent abuse of power. It is a specific structural principle, not the full description.
• D. Social democracy: This is a political ideology that combines democratic politics with social welfare and some economic regulation. It does not fit the description.

Step 4: Answer The correct answer is B. good governance.

Exam tip: When a question mentions "principles" such as accountability, transparency and rule of law, together with "development" and "decision-making", think good governance. Options like separation of powers and human rights are narrower parts of it.
