Explanation:

Question 1

Macronutrients (carbohydrates, proteins, fats) and vitamins are organic compounds. Organic compounds are primarily composed of carbon, hydrogen, and oxygen. The other options (boron, cadmium, lead; helium, gold, silver; silver, lead, mercury) are either non - essential, toxic, or inert elements not involved in the structure of macronutrients and vitamins.

Proteins, carbohydrates, and fats are the macronutrients that provide energy. Vitamins, minerals, and water do not provide energy. So the group with protein, carbohydrate, and fat is the one that provides energy.

Answer:

B. carbon, hydrogen and oxygen
