- BDirectly behind the storm
- CThe eye itself
- DThe right side relative to the storm's direction of movement✓ Correct
Explanation
Facing the direction the storm is moving, the right-hand semicircle (in the Northern Hemisphere) is the dangerous semicircle: winds are stronger there, and they tend to blow a vessel into the storm's path. The left side is the navigable semicircle.
