Final answer:
Individuals allergic to apples, oranges, and bananas might also be allergic to stone fruits such as cherries, peaches, and apricots due to similar allergens that can cause symptoms ranging from mild to severe, including anaphylaxis.
Step-by-step explanation:
If someone is allergic to apples, oranges, and bananas, they might also have allergies to other fruits. A common pattern in allergies is that individuals who are allergic to certain types of fruits may also react to other fruits with similar proteins. These are known as cross-reactive allergies. Among the options listed which include pineapples, grapes, melons, and stone fruits, the answer is d. Stone fruits.
Stone fruits, such as cherries, peaches, and apricots, contain similar allergens to apples. People who have a pollen fruit syndrome (also known as oral allergy syndrome) may experience allergic reactions to certain fruits and vegetables because the proteins in these foods are similar to those found in pollen. Symptoms of food allergies can include itching and swelling of the lips and mouth, vomiting, diarrhea, and more severe reactions like difficulty breathing and anaphylaxis. Hence, if an individual has allergies to apples, oranges, and bananas, they should be cautious with stone fruits as well.
