Final answer:
The correct statement matching the function to the organ of the digestive system is A, where the large intestine reabsorbs water to form solid waste. Statement B mistakenly identifies the duodenum as the middle section of the small intestine, while C incorrectly states that the jejunum is the first part. D is wrong because the gallbladder does not produce insulin; it is the pancreas that does.
Step-by-step explanation:
Among the provided statements, the one that matches the function to the organ of the digestive system is A. The large intestine reabsorbs water in the body to form solid waste. This is correct because the large intestine's main functions are to extract the water and mineral salts from undigested food, and to store waste material. The large intestine is composed of the cecum, colon, and rectum, where the colon is especially key in the water reabsorption process.
Statement B is incorrect as the duodenum is the first part of the small intestine and is where most chemical digestion takes place, not the middle section. The jejunum is the second part of the small intestine and primarily involved in nutrient absorption.
Statement C is inaccurate because the jejunum is not the first part of the small intestine; that designation belongs to the duodenum. The jejunum actually is the second part where most absorption occurs.
Statement D is also incorrect as the gallbladder does not produce insulin; it stores and concentrates bile. Insulin is produced by the pancreas.
