**Three-Dimensional Coordinate System for Electromagnetic Wave Analysis**

In the diagram, a three-dimensional coordinate system is depicted, comprising three axes labeled as follows:

- The positive x-axis is indicated as "+x" and points to the right.
- The negative x-axis is indicated as "-x" and points to the left.
- The positive y-axis is indicated as "+y" and points upwards.
- The negative y-axis is indicated as "-y" and points downwards.
- The positive z-axis is indicated as "+z" and points towards the viewer.
- The negative z-axis is indicated as "-z" and points away from the viewer.

---

**Problem Statement:**

Consider the three-dimensional coordinate system above. If at one point in time an electromagnetic wave is moving in the -x direction and has its E-field in the -z direction, in which direction is the B-field at the same point in time?

- ○ -x direction
- ○ -z direction
- ○ +x direction

In this context, the right-hand rule can be applied to determine the direction of the B-field (magnetic field).
