Step-by-step explanation:
The prognosis of chronic gastritis option (b) is variable and can depend on several factors including the underlying cause of the gastritis, the severity of the inflammation, and the individual's response to treatment. In some cases, chronic gastritis can be managed through lifestyle changes and medications, resulting in a good prognosis. However, if left untreated or if caused by certain conditions such as H. pylori infection, chronic gastritis can lead to complications such as ulcers, bleeding, or an increased risk of developing stomach cancer.
