Solution
The correct option is A Peptic ulcers
Helicobacter pylori (H. pylori) is a bacterium that causes chronic inflammation in the stomach and is a common cause of ulcers. H. pylori cause chronic inflammation (gastritis) by invading the lining of the stomach and producing a cytotoxin termed vacuolating cytotoxin A; this can lead to ulcer formation.
