Consider the following: 1. Demographic performance 2. Forest and ecology 3. Governance reforms 4. Stable government 5. Tax and fiscal efforts For the horizontal tax devolution, the Fifteenth Finance Commission used how many of the above as criteria other than population area and income distance?

Answer: B. The 15th Finance Commission used THREE additional criteria beyond population, area and income distance: Demographic Performance, Forest and Ecology, Tax and Fiscal Efforts. The 15th Finance Commission (Chairman: N.K. Singh) used the following weighted criteria for horizontal devolution of taxes among states for 2021-26: - Population (2011 census): 15% - Area: 15% - Income distance: 45% - DEMOGRAPHIC PERFORMANCE: 12.5% — rewards states with lower fertility rates - FOREST AND ECOLOGY: 10% — rewards states with greater forest cover - TAX AND FISCAL EFFORTS: 2.5% — rewards efficient state tax collection So among the five options in the question, the three additional criteria are 1 (Demographic Performance), 2 (Forest and Ecology), and 5 (Tax and Fiscal Efforts). Governance reforms (3) and Stable government (4) are NOT among the criteria. Source: 15th Finance Commission Report (Volume I) / Ministry of Finance.
