The image contains a mathematical expression and multiple-choice answers. The expression is:

\[
\left( \frac{\frac{2}{x^3y^{\frac{4}{3}}}}{x^2 y^3} \right)^{-\frac{3}{4}}
\]

To simplify this expression, let's break it down step by step:

### Step 1: Simplify the expression inside the brackets
The expression inside the brackets is a fraction:

\[
\frac{\frac{2}{x^3 y^{\frac{4}{3}}}}{x^2 y^3}
\]

This can be rewritten as:

\[
\frac{2}{x^3 y^{\frac{4}{3}}} \times \frac{1}{x^2 y^3} = \frac{2}{x^3 y^{\frac{4}{3}}} \times \frac{1}{x^2 y^3}
\]

Multiplying the \(x\) and \(y\) terms together:

\[
\frac{2}{x^{3+2} y^{\frac{4}{3} + 3}} = \frac{2}{x^5 y^{\frac{13}{3}}}
\]

### Step 2: Apply the outer exponent \(-\frac{3}{4}\)
Next, apply the exponent \(-\frac{3}{4}\) to both the numerator and denominator:

\[
\left( \frac{2}{x^5 y^{\frac{13}{3}}} \right)^{-\frac{3}{4}} = 2^{-\frac{3}{4}} x^{5 \times \frac{3}{4}} y^{\frac{13}{3} \times \frac{3}{4}}
\]

Simplifying the powers:

\[
= 2^{-\frac{3}{4}} x^{\frac{15}{4}} y^{\frac{-39}{12}} = 2^{-\frac{3}{4}} x^{\frac{15}{4}} y^{-\frac{13}{4}}
\]

### Step 3: Simplify the constants and terms
Now, rewrite the final expression as:

\[
\frac{x^{\frac{15}{4}}}{2^{\frac{3}{4}} y^{\frac{13}{4}}}
\]

### Step 4: Match with answer choices
The expression is closest to the form of choice C:

\[
\sqrt{x^2 y}
\]

Thus, the correct answer is **C**.
