Step-by-step explanation:
The question pertains to the number of food groups that are responsible for allergic reactions. The correct answer is (c) 8. There are eight most common food allergens that are recognized to provoke allergic reactions in sensitive individuals. These allergens include milk, eggs, peanuts, tree nuts, fish, shellfish, soy, and wheat.
Allergic reactions can range from mild symptoms like rashes to more severe conditions such as anaphylaxis, which can be life-threatening and requires immediate medical attention. Food allergies trigger an immune response to substances in food that are typically harmless to most people, but in those with allergies, the body reacts as if these substances are foreign invaders.
