Answer: (C)

Verified step by step guidance

1. Step 1: Begin by identifying the primary function of each organ system listed in the problem. For example, the urinary system is responsible for filtering blood and excreting waste as urine, while the endocrine system regulates hormones.
2. Step 2: Focus on the organ system responsible for water absorption. Recall that water absorption primarily occurs in the digestive system, specifically in the large intestine (colon).
3. Step 3: Understand the consequences of dysfunction in the digestive system. If the large intestine fails to absorb water properly, it can lead to chronic diarrhea due to excessive water remaining in the stool.
4. Step 4: Eliminate the other options based on their primary functions. The urinary system handles waste excretion, the endocrine system regulates hormones, and the respiratory system manages gas exchange. None of these are directly responsible for water absorption.
5. Step 5: Conclude that the correct answer is the digestive system, as it is the organ system primarily responsible for water absorption and its dysfunction can lead to chronic diarrhea.
