Which Universe term is correctly associated with scientific fact: “its gravity strongly bends spacetime”, and also with “a region where escape velocity exceeds the speed of light”?

Correct Answer: Option D — Black hole. Black hole is correct because it is its gravity strongly bends spacetime. It is also associated with a region where escape velocity exceeds the speed of light. Together, these two facts identify Black hole precisely within Universe. Why the other options are incorrect: Option A — Light-year: Light-year is approximately 9.46 trillion kilometres. It is also associated with a unit of distance, so these facts identify Light-year rather than Black hole. Option B — Milky Way: Milky Way is it belongs to the Local Group. It is also associated with a barred spiral galaxy, so these facts identify Milky Way rather than Black hole. Option C — Andromeda Galaxy: Andromeda Galaxy is it belongs to the Local Group. It is also associated with a spiral galaxy also catalogued as M31, so these facts identify Andromeda Galaxy rather than Black hole. Exam Takeaway: Link Black hole with “its gravity strongly bends spacetime” and “a region where escape velocity exceeds the speed of light” for quick revision.
