**Transcription for Educational Website:**

Choose the correct region of integration \( \int_{0}^{5} \int_{\sqrt{3x}}^{x} y \, dy \, dx \).

Assume that in each figure, the horizontal axis is the x-axis and the vertical axis is the y-axis.

**Graphs and Diagrams:**

1. **Top Left Graph:** 
   - A triangle above the line \( y = \sqrt{3x} \) and below the line \( y = x \). 
   - The base is along the x-axis.

2. **Top Right Graph:** 
   - A shaded region bounded above by the line \( y = x \), below by the line \( y = \sqrt{3x} \), extending horizontally from \( x = 0 \) to \( x = 5 \).
   - The area is triangular.

3. **Bottom Left Graph:**
   - A rectangular region extending horizontally, with a constant y-value independent of x. This does not depict the integration limits correctly.

4. **Bottom Right Graph:**
   - A triangle with its base along the line \( y = \sqrt{3x} \), extending up to the line \( y = x \), with integration limits from \( x = 0 \) to \( x = 5 \).

The correct region of integration is illustrated by the Top Right Graph.
