Which of the following substances is most likely to cause gastritis?
Correct Answer: D
Rationale: The correct answer is D, Nonsteroidal anti-inflammatory drugs (NSAIDs). NSAIDs are known to cause gastritis by irritating the stomach lining. Choice A, Milk, is unlikely to cause gastritis and is actually a common remedy for mild gastritis symptoms. Choice B, Bicarbonate of soda or baking soda, is often used to relieve heartburn and indigestion, not cause gastritis. Choice C, Enteric-coated aspirin, is less likely to cause gastritis compared to NSAIDs because the enteric coating helps protect the stomach lining from irritation.
