The correct answer is Both 1 and 2

Both Kwashiorkor and Marasmus are protein-energy malnutrition related disorders.

Protein-energy malnutrition is a condition that occurs when there is a deficiency of both protein and calories in the diet. This can lead to a range of nutritional disorders, including Kwashiorkor and Marasmus.

Kwashiorkor is a type of malnutrition that occurs in young children when they don’t get enough protein in their diet. Symptoms of Kwashiorkor include swelling of the belly, legs, and feet; skin and hair changes; and an enlarged liver.

Marasmus is a severe form of malnutrition that occurs when a person does not get enough calories and protein in their diet. Symptoms of Marasmus include severe weight loss, muscle wasting, and weakened immune function.

Xerophthalmia, on the other hand, is a condition that is caused by a deficiency of vitamin A. It can cause dryness and damage to the eyes, as well as other symptoms such as night blindness and an increased risk of infection.

So, the correct answer is option 3 – Both 1 and 2.
