What colors indicate the bow and stern lights on a boat?

The correct choice identifies that the bow and stern lights on a boat are indicated by red and green at the bow and white at the stern. Understanding the lighting on vessels is vital for safe navigation, especially at night or in reduced visibility conditions.

The red light is located on the port side (left side) of the boat, while the green light is on the starboard side (right side). This color coding helps other vessels determine the direction a boat is heading. For instance, if you see a red light, the boat is facing you from its left side, indicating it is traveling toward your position. Conversely, the white light serves as the stern light, which is positioned at the rear and helps with visibility from behind, ensuring that the boat is properly marked from all angles.

Other options do not correctly represent the standard colors used for boat navigation lights.
