The correct option is "increase in body size". Malnutrition is a condition in which an animal's diet is either deficient or excess in some essential nutrients needed for proper growth, maintenance, and reproduction. The general symptoms of malnutrition in animals include retarded growth, low production, susceptibility to diseases, and high mortality. These symptoms occur as a result of the animal's inability to obtain the necessary nutrients to sustain its normal metabolic functions. An increase in body size is not a symptom of malnutrition but rather an indication of overfeeding or obesity.
