Question

which of the following is an example of a harmful foreign invader?
eating peanuts with an allergy
being around animals with an allergy
getting a viral infection

Explanation:

To determine a harmful foreign invader, we analyze each option:

• "Eating peanuts with an allergy" involves a reaction to a food allergen, but peanuts are not foreign invaders in the context of infectious agents.
• "Being around animals with an allergy" is an allergic reaction to animal allergens (like dander), not a foreign invader causing infection.
• "Getting a viral infection" involves viruses, which are foreign (non - self) agents that invade the body and cause harm by disrupting normal cellular functions and triggering immune responses.

Answer:

C. Getting a viral infection
