Which one among the following combinations most appropriately represent the components of balanced diet ?

A balanced diet is defined as a diet that contains all the essential nutrients in the correct proportions required for the growth, repair, and maintenance of the body. According to NCERT and health standards, a complete balanced diet must consist of seven key components:

• Macronutrients: Carbohydrates (primary energy source), Proteins (body building and repair), and Fats (concentrated energy and insulation).
• Micronutrients: Vitamins and Minerals (essential for metabolic regulation and immunity).
• Supporting Components: Dietary Fibres (crucial for digestion and preventing constipation) and Water (essential for hydration, temperature regulation, and nutrient transport).

Option A is the most comprehensive choice as it includes all seven elements. Other options are incomplete; for instance, Option B misses fibres and water, while Option D misses carbohydrates, which are the body's main fuel source.
