Which of the following is a protein?

Explanation:
Proteins are nutrients made of amino acids that help build and repair body tissues. Meat provides a rich source of animal protein with all essential amino acids needed for growth and maintenance. Rice is mainly a carbohydrate source and contains only small amounts of protein. Oil is fat, a different macronutrient. Vitamin A is a micronutrient, not a protein. Therefore, meat is the correct choice because it supplies the protein.
