(A) The sun.
(B) Sagittarius.
(C) (There is a tie.)
(D) (Neither will set, as they are circumpolar.)
Correct answer (highlight to unhide): (A)
Generally objects low in the southern sky, located to the east of the meridian will set after objects that lie on or towards the west of the meridian. (This can be demonstrated using a planisphere (starwheel) for Sagittarius and Scorpius, as the sun would take approximately one month to move to the next zodiac constellation, and will remain within Scorpius during this date.)
