According to Gopalan's Hypothesis of Protein Energy Malnutrition (PEM):
- Statement I is incorrect. Marasmus is primarily caused by a lack of total caloric intake, and it is not typically the result of dysadaptation. Kwashiorkor, on the other hand, is caused by protein deficiency despite adequate caloric intake, and is a result of the body's adaptation to starvation.
- Statement II is correct. Kwashiorkor results from protein deficiency, which leads to the breakdown of protective mechanisms like the immune system. Free radicals are also involved in causing oxidative damage to cells, further impairing the protective mechanisms of the body.
Thus, the correct answer is (4) Statement I is incorrect but Statement II is correct.
