Question

Match the cell types in Group I with the processes in Group II.

Group I
(p) NK cells
(q) B cells
(r) Mast cells
(s) Neutrophils

Group II
(i) Antibody production
(ii) First cells to be recruited at the site of infection
(iii) Antibody-dependent cell-mediated cytotoxicity
(iv) Histamine production

• A. (p)–(ii); (q)–(i); (r)–(iii); (s)–(iv)
• B. (p)–(ii); (q)–(i); (r)–(iv); (s)–(iii)
• C. (p)–(iii); (q)–(i); (r)–(iv); (s)–(ii)
• D. (p)–(iii); (q)–(i); (r)–(i); (s)–(iv)

Hint:

Remember: NK \(\to\) ADCC; B \(\to\) antibodies; Mast \(\to\) histamine; Neutrophils \(\to\) first responders in acute inflammation.

Answer 1

The Correct Option is C

NK cells mediate ADCC via Fc receptors \(⇒\) (p)–(iii).
B cells are the lymphocytes responsible for antibody production \(⇒\) (q)–(i).
Mast cells store and release histamine from granules \(⇒\) (r)–(iv).
Neutrophils are typically the first recruited innate cells to infection sites \(⇒\) (s)–(ii).
Therefore the matching is (p)–(iii), (q)–(i), (r)–(iv), (s)–(ii) \(⇒\) option (C).
