Answer: (A)

Verified step by step guidance

1. Step 1: Understand the context of gastric cancer. Gastric cancer, also known as stomach cancer, is a disease where malignant cells form in the lining of the stomach. It is influenced by various risk factors, including environmental, dietary, and genetic factors.
2. Step 2: Analyze the first statement: 'Helicobacter pylori infection is a significant risk factor for developing gastric cancer.' Helicobacter pylori is a bacterium that infects the stomach lining and is strongly associated with chronic inflammation, ulcers, and an increased risk of gastric cancer. This statement is scientifically accurate.
3. Step 3: Evaluate the second statement: 'Gastric cancer rarely metastasizes to other organs.' This is incorrect because gastric cancer can and often does metastasize to other organs, such as the liver, lungs, and lymph nodes, especially in advanced stages.
4. Step 4: Assess the third statement: 'Dietary intake of fresh fruits and vegetables increases the risk of gastric cancer.' This is incorrect because fresh fruits and vegetables are generally protective against gastric cancer due to their high content of antioxidants, vitamins, and fiber.
5. Step 5: Examine the fourth statement: 'Gastric cancer is most commonly diagnosed in individuals under 30 years old.' This is incorrect because gastric cancer is more commonly diagnosed in older individuals, typically those over the age of 50, and is rare in younger populations.
