- A. At least 2 meters vertically higher than the forward masthead light

- C. At the same height as the forward masthead light but at or near the side of the vessel
- D. Not less than 4 meters above the hull and forward of the masthead light
Why B is correct
33 CFR §84.02(g) requires sidelights to be placed at least 1 meter lower than the forward masthead light and not so low as to be interfered with by deck lights. 33 CFR §84.03(b) further requires that on a vessel of 20 meters or more, sidelights shall not be placed in front of the forward masthead lights.
