Why D is correct
COLREGs Rule 28 prescribes three all-round red lights in a vertical line, or a cylinder, carried in addition to the lights required for a power-driven vessel under Rule 23. The shape is a cylinder, not a ball, cone, or diamond. This rule has no Inland counterpart; Inland Rule 28 is reserved.
