Answer:

The food group that serves as our body's best source of energy is fats and oils.

• Energy set free from sugars, fats, proteins, and other natural mixtures are known as food energy. Carbs, fats, and proteins are the three significant calorigenic supplements.

• At the point when carbs, fats and proteins in food are scorched totally with an adequate measure of oxygen, it discharges energy or food calories that are communicated in kilojoules or kilocalories.

• The primary function of fat is to supply energy.
• Each gram of fat = 9 kcal. The high density and low solubility of fats make them an ideal form in which to store energy.

• Not only are fats as such stored in adipose tissue but many glucose and amino acid are not promptly utilized and are also synthesized into fats and stored.
• Fats have thus the best measure of food energy per mass, up to 9 kcal/g.

• The majority of the sugars and proteins have roughly 4 kcal. g⁻¹, while filaments have lesser energy.

• Oil and Fats and Nuts and Oilseeds are the most extravagant in energy as far as kCal per grams they contain fats.

• Consequently, we presume that Oil and Fats and Nuts and Oilseeds are the most extravagant in energy as far as kcal per grams.

Hence the most appropriate option would be Oil and Fats.
