Correct answer:
Pollen is an inhalant type of allergen. Hence, option (d) is correct.
Option (d) is given as “Inhalant”.
Explanation of Solution
Justify reason for the correct statement:
The pollen is light and is produced by plants for the purpose of reproduction. These pollens are light and travel through air and get inhaled during breathing. It causes irritation in the respiratory tract.
Hence, option (d) is correct.
Justify reasons for the incorrect statements:
Option (a) is given as “contactant”.
Contact allergens enter the body through the skin and these allergens generally cause skin rashes or itching but pollen causes irritation in the respiratory tract. Hence, it is a wrong answer.
Option (b) is given as “ingestant”.
Ingestants are the food-based allergens and enter the body through food consumption. It basically consists of milk, peanuts, wheat nuts and many more. But pollen is not a consumable item. Hence, it is a wrong answer.
Option (c) is given as “Injectants”
Injectants enter the body through insect bite, drugs or serum. Hence, it is a wrong answer.
Hence, options (a), (b), and (c) are incorrect.
The pollen is a type of inhalant allergen. They enter the body while breathing and cause irritation in the respiratory tract.
