Multiple choice

What does "deficiency'' mean in the passage?

Directions: Read the passage given carefully and answer the question that follows.

The diet which contains adequate amount of all the important nutrients like carbohydrates, fats, proteins, minerals and vitamins, sufficient for the normal growth and development of the body is called a balanced diet. The constituents of balanced diet are - Carbohydrates, Fats, Proteins, Minerals (Salts), Vitamins, Water and Roughage, Carbohydrates are the compounds of carbon, hydrogen and oxygen. They are the main source of energy. The fats are the compounds of carbon, hydrogen and oxygen. The main function of fats in the body is to provide a steady source of energy. The proteins are highly complex organic compounds of carbon, hydrogen, oxygen and nitrogen. Proteins are very important for the growth and repair of the body. Kwashiorkor is a disease which occurs due to the deficiency of proteins in the diet of children whereas Marasmus occurs in the infants (small children) due to the deficiency of proteins. The metals, non-metals and their salts are called minerals. Our body needs minerals for its proper functioning.
