- BShe shall use available working or equivalent lights to illuminate her decks✓ correct
- CShe shall exhibit a second all-round white light at the masthead
- DShe may, at her discretion, illuminate her decks but is not required to do so

33 CFR §83.30(c) states that a vessel of 100 meters or more in length shall use available working or equivalent lights to illuminate her decks. For vessels under 100 meters this is optional; for vessels 100 meters and over it is mandatory.
