c) causes mostly symptomatic infections.
d) affects only females.

Explanation:

Question 15

To determine the correct answer, we analyze each option:

• Option a: Urine flushes out microbes from the urinary system, reducing microbial load.
• Option b: Urine contains lysozyme, an enzyme with antimicrobial properties.
• Option c: Lactoferrin, which has antimicrobial effects, is present in urine.

Since all (a, b, c) contribute to urine's antimicrobial action, the correct option is d.

Analyzing each option:

• Option a: Trichomonas vaginalis is a flagellated (not ciliated) protozoan.
• Option b: It is sexually transmitted, making this correct.
• Option c: Infections can be asymptomatic in many cases.
• Option d: It can affect both males and females (though more symptomatic in females).

So the correct option is b.

Answer:

d) all of the above.
