a. 1:1
b. 1:10
c. 1:750
d. 10:100
e. 1:250

Answer: (c) 1:750. Benzalkonium chloride is indicated for prophylaxis and treatment of skin infections. It is antimicrobial against a wide variety of bacteria, fungi and protozoa.

The antimicrobial action of benzalkonium chloride is attributed to its ability to inactivate bacterial enzyme.
