Verified by Experts

The correct Answer is:
B
Excessive stimulation of vagus nerve in human may lead to peptic ulcer. Vagal stimulation increases peristalsis which in excess, secretes more HCl and pepsin from stomach. These causes erosion through protective barrier of mucus and muscularis muscosa into the submucosa which lead to peptic ulcer.
