The Bowman's capsule is a part of the :

Options

A. uriniferous tubule and the site of reabsorption of water and glucose
B. uriniferous tubule and the site of filtration of various blood constituents
C. liver and is the site of secretion of bile juice
D. lung and the site of gaseous exchange

Explanation

**Step-by-Step Solution:**

1. **Identify the Structure**: The Bowman's capsule is a structure found in the kidney. It is part of the nephron, which is the functional unit of the kidney.

2. **Understand the Function**: The primary function of the Bowman's capsule is to facilitate the filtration of blood. It collects the filtrate from the blood that passes through the glomerulus, which is a network of capillaries.

3. **Analyze the Options**:
- **Option 1**: "Uriniferous tubule and the site of reabsorption of water and glucose." - This is incorrect because the Bowman's capsule is not primarily involved in reabsorption.
- **Option 2**: "Uriniferous tubule and the site of filtration of various blood constituents." - This is correct as Bowman's capsule is indeed part of the uriniferous tubule and is responsible for the filtration process.
- **Option 3**: "Liver and is the site of secretion of bile juice." - This is incorrect as Bowman's capsule is not part of the liver.
- **Option 4**: "Lung and the site of gaseous exchange." - This is also incorrect as Bowman's capsule is not part of the lungs.

4. **Conclusion**: Based on the analysis, the correct answer is **Option 2**: "Uriniferous tubule and the site of filtration of various blood constituents."
