Why is the combination of grain, pulse and vegetable useful in traditional Indian meals?

Correct answer: It can provide a balance of energy, protein and micronutrients

The direct answer is A: grain, pulse, and vegetable together can provide energy, protein, vitamins, minerals, and fibre in a balanced meal. Grain such as rice or wheat mainly supplies carbohydrate and energy. Pulses such as dal, beans, or lentils supply useful protein and also some minerals and fibre. Vegetables add vitamins, minerals, fibre, water, and protective nutrients. Step by step, different food groups contribute different nutrients, so variety improves the overall meal. A is correct because it says “can,” not that every meal has a perfect balance. B is wrong because variety generally supports balance. C is wrong because these foods provide nutrition, not merely decoration. D is wrong because they do not always stop digestion; suitable portions and preparation can support normal digestion. Memory cue: grain gives energy, pulse gives protein, vegetables add protective nutrients.
