The exaggerated response of the ______ system to certain antigens present in the environment is called allergy.

Show answer & explanation

Correct answer: B

Explanation

The correct answer is option 2 i.e. immune.

Explanation:

  • Allergy is an exaggerated or hypersensitive response of the immune system to certain harmless antigens (called allergens) present in the environment, such as pollen, dust, or certain foods.

  • The immune system mistakenly identifies these antigens as threats and overreacts, causing symptoms like sneezing, itching, swelling, or even severe reactions.

  • Other systems like the nervous, digestive, or cardiovascular systems may be affected as a result of allergic reactions, but the primary response is by the immune system.
