Final answer:
The bacterium Helicobacter pylori is the most common cause of chronic inflammatory disease of the stomach, potentially leading to ulcers and increased stomach cancer risk. Option B is correct
Step-by-step explanation:
The common cause of the chronic inflammatory disease of the stomach is Helicobacter pylori (H. pylori). This gram-negative bacterium is known for its ability to survive in the highly acidic environment of the stomach by producing urease and modifying its environment to be less acidic.
This allows it to cause chronic gastritis, which can lead to the development of ulcers in the stomach and duodenum as well as increase the risk for stomach cancer. The connection between H. pylori and these gastrointestinal issues was such a significant medical discovery that it led to a Nobel Prize awarded to scientists Robin Warren and Barry J. Marshall for uncovering this relationship.
The common cause of the chronic inflammatory disease of the stomach is Helicobacter pylori. This bacterium is able to tolerate the highly acidic environment of the stomach and is associated with chronic gastritis, ulcers, and an increased risk of stomach cancer. H. pylori produces urease and other enzymes that modify its environment to make it less acidic, allowing it to survive.
