The key details are that the infant was born at 37 weeks gestation, has had normal growth and development so far, and is currently being exclusively breastfed and receiving vitamin D supplementation. At 6 months of age, complementary foods can be introduced along with continued breastfeeding. Vitamin D supplementation should be continued since breast milk is not a significant source of vitamin D. Cows milk is not recommended before 12 months of age. Vitamin C supplementation is generally not needed if the infant is receiving a varied diet. Therefore, the correct answer should be to introduce solid foods and continue vitamin D supplementation.B: Introduce solid foods and continue vitamin D
