Match the viruses in Group I with their host cell receptors in Group II:
Group I
P. Hepatitis A virus
Q. Human immunodeficiency virus
R. Rabies virus
Group II
1. Heparan sulphate
2. Acetylcholine receptor
3. CD4 protein
4. Alpha-2 macroglobulin
Options:
(A) P-1, Q-3, R-2, S-4
(B) P-3, Q-4, R-1, S-2
(C) P-4, Q-3, R-2, S-1
(D) P-2, Q-3, R-1, S-4
Answer
Answer: (C) P-4, Q-3, R-2, S-1
Explanation: Hepatitis A virus binds to alpha-2 macroglobulin (4), HIV binds to CD4 protein (3), Rabies virus binds to acetylcholine receptor (2), and Herpes simplex virus type I binds to heparan sulphate (1).
