(b) उत्पन्नातील वाढ
(c) अन्नधान्याचे कमी उत्पादन
(d) अन्नधान्याच्या कमी किंमती
पर्यायी उत्तरे :

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

Key Points:
• Drivers of Foodgrain Demand: In macroeconomics, aggregate demand for staple food is fundamentally driven by consumer base expansion and purchasing power:
• Rapid Population Growth: Directly multiplies the absolute number of consuming units requiring daily nutritional sustenance (Statement a).
• Rise in Income Level: As household per capita incomes rise, especially among lower- and middle-income deciles, spending on calorie intake and quality foodgrains increases (Statement b).
• Supply vs. Demand Factors: Low foodgrain production (Statement c) affects supply, not aggregate demand. Low foodgrain prices (Statement d) is not a structural long-term driver in India, where food inflation has historically prevailed.
• Official Key: Statements (a) and (b) are correct, validating Option (1).
• Key Takeaway: Aggregate foodgrain demand has risen primarily due to rapid population expansion and increasing per capita income levels.
