Civil twilight starts at 1812 zone time on 26 August, Your DR position at that time is LAT 21°06'S, LONG 14°56'W. Which statement concerning the planets available for evening sights is TRUE?

Official USCG Answer & Rule Citation

Correct Answer: Option C — Venus may be identified from Saturn and Jupiter because it is the brightest.

Venus is significantly brighter than Jupiter or Saturn due to its proximity to the Sun and Earth and its high albedo. During twilight, this extreme magnitude makes Venus easily identifiable, whereas other planets require more careful observation or calculation to distinguish from bright stars in the evening sky.
