To determine which reflections transform quadrilateral ABCD into quadrilateral EFGH, we need to look at the properties of reflections in a coordinate plane.

Assume:

- Quadrilateral ABCD is located in the second quadrant (where x < 0 and y > 0).
- Quadrilateral EFGH is located in the fourth quadrant (where x > 0 and y < 0).

To go from the second quadrant to the fourth quadrant, the following transformations should occur:

1. **Reflect over the line y=0** (the x-axis): This reflection will take points in the second quadrant to the third quadrant. For example, a point (x, y) will be reflected to (x, -y). So a point in the second quadrant will move to the third quadrant.

2. **Reflect over the line x=0** (the y-axis): This reflection will take points from the third quadrant to the fourth quadrant. For example, a point (x, y) will be reflected to (-x, y), flipping the x-coordinate to negative.

3. **Reflect over the line y=x**: This transformation will swap the x and y coordinates of the shape, but in our case, the quadrilateral is already in place after the first two transformations.

Given these necessary reflections, we can see:

- The transformation sequence that reflects over the line y = 0 first would move ABCD to the third quadrant.
- The subsequent reflection over the line x = 0 would then move it to the fourth quadrant.

Now let's compare the given options:

**Option B**
> Reflect ABCD first over the line y=0, then over the line y=x.

In this option, the first reflection correctly takes ABCD to the third quadrant (which is not what we want) but does not help to get to EFGH.

**Option A**
> Reflect ABCD first over the line x=0, then over the line y=x.

This will not work because the first reflection takes the shape to the left instead of down.

**Option C**
> Reflect ABCD first over the line x=0, then over the line y=0.

This option does not correctly move the shape to the desired position either.

**Option D**
> Reflect ABCD over the line y=x.

This single reflection won't be sufficient to achieve the transformation needed.

Based on the analysis:

The **correct transformations** are achieved by reflecting ABCD **first over y=0 (the x-axis)**, then **over x=0 (the y-axis)**. This will correctly position ABCD transformed into EFGH.

Thus, the **correct response is**:
**Reflect ABCD first over the line y=0, then over the line y=x.**
