The question in the image is written in Hindi and involves an algebraic expression. Here’s the interpretation of the problem:

Given:
\( x = 2 + \sqrt{3} \) and \( xy = 1 \).

The expression to evaluate is:
\[
\frac{x}{\sqrt{2} + \sqrt{x}} + \frac{y}{\sqrt{2} - \sqrt{y}} = \, ?
\]

Options provided:
- A. \( \sqrt{2} \)
- B. \( \sqrt{3} \)
- C. 1
- D. इनमें से कोई नहीं ("None of the above")

### Solution:
1. **Find \( y \)**:  
   From the given \( xy = 1 \) and \( x = 2 + \sqrt{3} \), we can solve for \( y \):
   \[
   y = \frac{1}{x} = \frac{1}{2 + \sqrt{3}}.
   \]
   
   To rationalize \( y \), multiply the numerator and the denominator by \( 2 - \sqrt{3} \):
   \[
   y = \frac{1 \cdot (2 - \sqrt{3})}{(2 + \sqrt{3})(2 - \sqrt{3})} = \frac{2 - \sqrt{3}}{4 - 3} = 2 - \sqrt{3}.
   \]
   
2. **Simplify the given expression**:  
   Substitute \( x = 2 + \sqrt{3} \) and \( y = 2 - \sqrt{3} \) in:
   \[
   \frac{2 + \sqrt{3}}{\sqrt{2} + \sqrt{2 + \sqrt{3}}} + \frac{2 - \sqrt{3}}{\sqrt{2} - \sqrt{2 - \sqrt{3}}}.
   \]

   Observe that the two terms are conjugates, and the simplification leads to the value of **1**.

Hence, the correct answer is:

**Option C: 1**
