Option 1 states that Kwashiorkor disease in children is caused by sufficient carbohydrates but less fats in the diet. This is incorrect. Kwashiorkor disease is primarily caused by a deficiency in protein intake, not fats.

Option 2 correctly states that Kwashiorkor disease is caused by sufficient carbohydrates and fats but deficient proteins in the diet. Lack of protein in the diet leads to a lack of essential amino acids, which are necessary for proper growth and development in children. As a result, children with Kwashiorkor disease often experience symptoms such as swelling, fatigue, poor growth, and mental changes.

Option 3 suggests that sufficient vitamins but deficient fats in the diet cause Kwashiorkor disease. While vitamins are important for overall health, Kwashiorkor is primarily a protein deficiency disorder, not specifically related to fat intake.

Option 4 states that sufficient fats but deficient vitamins in the diet cause Kwashiorkor disease. Again, this is incorrect as Kwashiorkor is primarily caused by a lack of protein in the diet.

In conclusion, option 2 is the correct answer as it accurately identifies that Kwashiorkor disease is caused by sufficient carbohydrates and fats but deficient proteins in the diet.
