Diabetes is detected using ......by testing urine of patients

Options

A. Fehling's solution
B. Tollen's reagent
C. Benedict's solution
D. Baeyer's reagent

Explanation

To determine how diabetes is detected through urine testing, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about a specific solution used to detect diabetes through urine testing.

2. **Identifying the Options**: The options provided are:
- A) Felling solution
- B) Tolerance reagent
- C) Benedict solution
- D) Bayer's reagent

3. **Researching Each Option**:
- **Felling Solution**: This is primarily used for detecting reducing sugars but is less stable than Benedict's solution.
- **Tolerance Reagent**: This is not commonly used for urine tests related to diabetes.
- **Benedict Solution**: This solution contains copper(II) sulfate (CuSO4), sodium carbonate (Na2CO3), and sodium citrate. It is used specifically to test for glucose in urine.
- **Bayer's Reagent**: This is not a standard reagent for glucose detection in urine.

4. **Choosing the Correct Answer**: Among the options, the Benedict solution is well-known for its ability to detect glucose in urine, which is a key indicator of diabetes.

5. **Conclusion**: Therefore, the correct answer is **C) Benedict solution**.
