Why the other options are incorrect: Option B — Black hole: Black hole 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, so these facts identify Black hole rather than Crab Nebula. Option C — 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 Crab Nebula. Option D — 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 Crab Nebula. Exam Takeaway: Link Crab Nebula with “a supernova remnant” and “located in the constellation Taurus” for quick revision.
