A9-month-old infant is seen in the emergency department after developing urticaric rash with cough and wheezing. when collecting the history of events prior to the sudden onset of the rash with cough and wheezing, the mother states they were "feeding the baby new foods." which food is the possible cause of this type of reaction in the infant?
a) potatoes
b) green beans
c) spinach
d) peanut butter

Considering the child's age and symptoms, it appears that this is an allergic reaction. It can be inferred that among the options, the food most likely to trigger these symptoms is peanut butter.
