पर्यायी उत्तरे :

The correct answer is Option A (Both a and b).

Key Points:
• Evaluating India's economic performance across the 63-year planning era (1950–51 to 2013–14):
• Statement a is correct: The compound average annual growth rate of national income (real GDP/NNP) over this aggregate 63-year period averaged roughly 4.7% per annum.
• Statement b is correct: During the first three decades of planning (1950 to 1980), national income grew at an average rate of roughly 3.5% per annum, popularly characterized by Prof. Raj Krishna as the 'Hindu rate of growth'.
• Statement c is incorrect: Due to rapid population expansion (averaging ~2% annually), per capita income grew at a much lower average rate (around 2.5%–2.8% per annum over the 63-year period), not 4.8%.
• Therefore, both statements a and b are correct.
• Key Takeaway: Over 63 years of planning, national income grew at ~4.7% per annum and averaged ~3.5% in the first three decades (both a and b are correct).
