| LIST-I | LIST-II |
|---|---|
| Terms | Relationships |
| A. Common cold | I. Antiviral protein |
| B. Polymorpho-nuclear leukocytes | II. Serotonin |
| C. Interferons | III. Rhino virus |
| D. Mast Cells | IV. Cellular barrier |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → A-III, B-IV, C-I, D-II
(A) Common cold — this matches (III) Rhino virus. Rhinoviruses infect the nose and the respiratory passage and cause the common cold.
(B) Polymorpho-nuclear leukocytes — this matches (IV) Cellular barrier. These white blood cells, the neutrophils, swallow and destroy microbes. They are part of the cellular barriers of innate immunity.
(C) Interferons — this matches (I) Antiviral protein. Virus-infected cells secrete these proteins, and they protect the non-infected cells from further viral infection.
(D) Mast Cells — this matches (II) Serotonin. In an allergy, mast cells release chemicals such as histamine and serotonin.
