Why B is correct
33 CFR §83.03(l) defines 'restricted visibility' as any condition in which visibility is restricted by fog, mist, falling snow, heavy rainstorms, sandstorms, or any other similar causes. The rule does not set a specific distance threshold, and nighttime is not included in the definition.
