Correct Answer: Option D — Andromeda Galaxy. Andromeda Galaxy is correct because it is it belongs to the Local Group. It is also associated with a spiral galaxy also catalogued as M31. Together, these two facts identify Andromeda Galaxy precisely within Universe. Why the other options are incorrect: Option A — Sun: Sun is sunlight reaches Earth in about 8 minutes 20 seconds. It is also associated with a G-type main-sequence star, so these facts identify Sun rather than Andromeda Galaxy. Option B — Sirius: Sirius is it is about 8.6 light-years from Earth. It is also associated with a binary star system, so these facts identify Sirius rather than Andromeda Galaxy. Option C — Proxima Centauri: Proxima Centauri is it is about 4.24 light-years away. It is also associated with a red dwarf star, so these facts identify Proxima Centauri rather than Andromeda Galaxy. Exam Takeaway: Link Andromeda Galaxy with “it belongs to the Local Group” and “a spiral galaxy also catalogued as M31” for quick revision.
