Question
The image consists of four diagrams labeled A, B, C, and D. Each diagram represents a cross-section of tectonic plates interacting at a trench with a labeled "Wadati-Benioff" zone. These zones are regions where earthquakes are commonly generated, and they occur at convergent plate boundaries where one plate subducts beneath another.

- **Diagram A** shows the surface with a trench to the right. Beneath the surface, the Wadati-Benioff zone is depicted with a curved arrow moving to the left, indicating the subduction of a tectonic plate.

- **Diagram B** also shows the surface with a trench to the right. The Wadati-Benioff zone is shown below, with a leftward pointing arrow indicating motion.

- **Diagram C** is similar, depicting a trench to the right. The underlying curved arrow in the Wadati-Benioff zone indicates a rightward subduction motion.

- **Diagram D** has a trench to the right, with the Wadati-Benioff zone shown below. A straight arrow points downwards, indicating the direction of subduction.

Below these diagrams is the question: "Which cartoon correctly illustrates the tectonic motion associated with a Wadati-Benioff zone?"

There are four multiple-choice options:
- ○ A
- ○ B
- ○ C
- ○ D
