C
Feedback:
H. pylori appears to secrete an enzyme that depletes gastric mucus, making the mucosal layer more susceptible to erosion.

Answer to Question 2

A
Hepatitis A is transmitted via the fecal-oral route. Hepatitis B and D are transmitted parenterally or sexually. Hepatitis C is transmitted via blood or serum (sharing of contaminated needles, ra-zors, toothbrushes, nail files, barber's scissors, tattooing equipment, body piercing, or acupunc-ture needles).
