Answer: c. Five months
Step-by-step explanation:
The digestive system in infants is weak and is incapable of digesting solid foods in young age typically in one or two months after birth. According to the american academy of pediatrics. The infant must be fed with solid foods in 4-6 months. It also depends on how the infant responds when fed with different solid foods. The solid food must be in highly diluted form, like in a meshed form and must be boiled so that the infant can swallow and digest the food easily.
