The region with gravity so strong that light cannot escape, formed from a very massive star's collapse?

• A. Neutron Star
• B. Black Hole
• C. Nebula
• D. White Dwarf

Answer: (B)

When gravity becomes so intense that nothing can escape even light, you’re at the boundary of a black hole. This happens when a very massive star collapses under its own gravity to a tiny volume, increasing the escape velocity beyond the speed of light. The region around it is the event horizon, beyond which nothing can get out. That description fits a black hole perfectly. Neutron stars are also incredibly dense, but light can still escape from their surface, and they form from less massive stars. Nebulae are just clouds of gas and dust, not collapsed remnants trapping light. White dwarfs are supported by electron degeneracy pressure and come from even less massive progenitors, again not trapping light.
