Option 1: A huge black star that has zero acceleration due to gravity on its surface. This statement is incorrect. A black hole is not a star, but rather an astronomical object that forms when a massive star collapses under its own gravity.

Option 2: A star that has moderate acceleration due to gravity on its surface. This statement is incorrect. A black hole is formed when a star collapses into itself, resulting in a singularity with incredibly strong gravitational forces.

Option 3: A star that has collapsed into itself and has large acceleration due to gravity on its surface. This statement is correct. When a massive star runs out of nuclear fuel, it can undergo a supernova explosion. If the remnant core of the star is massive enough, it will collapse under its own gravity to form a black hole. The black hole has an intense gravitational pull, which leads to significant acceleration due to gravity on its surface.

Option 4: A star that has collapsed into itself and has zero acceleration due to gravity on its surface. This statement is incorrect. As mentioned earlier, a black hole has a tremendous amount of gravity and consequently exerts a strong gravitational pull. It is anything but zero.

In conclusion, option 3 accurately describes a black hole as a star that has
