Which Universe term is correctly associated with classification or identity: “a region where escape velocity exceeds the speed of light”, and also with “often formed from the collapse of a massive star”?

Correct Answer: Option A — Black hole. Black hole is correct because it is a region where escape velocity exceeds the speed of light. It is also associated with often formed from the collapse of a massive star. Together, these two facts identify Black hole precisely within Universe. Why the other options are incorrect: Option B — Light-year: Light-year is a unit of distance. It is also associated with used for distances between stars and galaxies, so these facts identify Light-year rather than Black hole. Option C — Milky Way: Milky Way is a barred spiral galaxy. It is also associated with the galaxy containing the Solar System, so these facts identify Milky Way rather than Black hole. Option D — Andromeda Galaxy: Andromeda Galaxy is a spiral galaxy also catalogued as M31. It is also associated with the nearest large galaxy to the Milky Way, so these facts identify Andromeda Galaxy rather than Black hole. Exam Takeaway: Link Black hole with “a region where escape velocity exceeds the speed of light” and “often formed from the collapse of a massive star” for quick revision.
