what effect does introducing food allergens to the skin have on the body?
a the body is less likely to see the food allergen as dangerous.
b the body is less likely to react to the food allergen in the diet.
c the body is more likely to identify the food allergen as harmful.
d the body is more likely to let the food allergen cross its barrier.

Explanation:

The passage states that introducing allergens in the diet early (so gut sees it) vs skin reaction. If allergens are introduced to the skin, the body is more likely to identify the food allergen as harmful (since skin reaction context implies a more reactive/harmful perception, matching option C's logic: skin exposure makes body see it as harmful, while diet early is better to avoid that). Option A is wrong (skin would see it as more dangerous). Option B is wrong (skin exposure would make diet reaction more likely? No, the logic is skin reaction is bad, so skin exposure makes body see allergen as harmful). Option D: "let cross its barrier" is not supported; the focus is on perception of harm, not barrier crossing. So C is correct.

Answer:

C. The body is more likely to identify the food allergen as harmful.
