• A. cough
• B. itching
• C. fever
• D. inflammation

Hint:

Differentiate between a root cause and its symptoms. Inflammation is the underlying process, while itching, coughing, and sneezing are the resulting symptoms. Questions often test your understanding of this distinction.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
This question asks about the underlying biological process that occurs during an allergic reaction, as explained in the chapter 'Allergy'.

Step 2: Detailed Explanation:
An allergy is an overreaction of the immune system to an allergen. When the body encounters an allergen, the immune system releases chemicals like histamine.
These chemicals cause a cascade of effects in the body. The primary effect is inflammation, which is the body's protective response to remove harmful stimuli.
This inflammation is what produces the visible and felt symptoms of an allergy. For example, itching (B) is a symptom caused by inflammation of the skin. A cough (A) can be caused by inflammation in the airways. Inflammation is the root cause, while the other options are specific symptoms of it.

Step 3: Final Answer:
The violent reaction during an allergy leads to inflammation.
