The question asks about the transformation of trapezoid $LMNO$, and the image shows two trapezoids on the coordinate plane. From the image, we can see that trapezoid $L'M'N'O'$ is a transformed version of $LMNO$.

Here's an analysis of the transformation:

• The original trapezoid $LMNO$ appears to be reflected downward.
• Each corresponding point of the trapezoid (e.g., $L$ to $L'$, $M$ to $M'$) appears to be reflected across the $x$-axis.

Thus, this is a reflection over the x-axis. The correct answer is B: reflection over the x-axis.

Would you like more details or further clarifications? Here are five related questions to explore the topic further:

1. What is the general rule for reflecting a point over the x-axis?
2. How would the coordinates of $LMNO$ change if it were reflected over the y-axis?
3. What are the coordinates of trapezoid $LMNO$ and its reflection $L'M'N'O'$?
4. How do you distinguish between reflection over the origin and over an axis?
5. Can you perform other transformations, such as rotations, to get the same image?

Tip: When reflecting a figure over the x-axis, each point's y-coordinate changes sign, but the x-coordinate remains the same.
