The answer is the fourth one (or D): food.

Explanation for each option:

  • Water: While water is essential for life and various bodily functions, it does not provide calories or serve as a direct source of energy.
  • Minerals: Minerals are important for various physiological processes, but they do not provide calories or energy.
  • Sunlight: Sunlight is crucial for the synthesis of vitamin D in humans and is the primary energy source for plants through photosynthesis, but humans do not directly obtain calories from sunlight.
  • Food: Food is the correct answer because it contains macronutrients (carbohydrates, proteins, and fats) that are metabolized by the body to produce energy in the form of calories.

Summary: Humans use the calories they obtain from food as their source of energy.
