The correct answer is (C) vegetables and fruits.
Vegetables and fruits are widely recognized as the most significant sources of a broad spectrum of vitamins, minerals, antioxidants, and dietary fiber for vegetarians and non-vegetarians alike. A varied intake of different types of vegetables and fruits ensures adequate supply of essential micronutrients.
While black gram, wheat, rice, mustard, soya bean, and milk provide various nutrients (protein, carbohydrates, some vitamins/minerals), they do not collectively offer the same wide variety and abundance of vitamins and minerals as a diverse diet rich in vegetables and fruits. Soya bean is excellent for protein, and milk for calcium and some vitamins (for lacto-vegetarians), but fruits and vegetables are fundamental for overall micronutrient intake.
