Which among the following decide(s) whether a collapsing star would become a white dwarf or a black hole?
1. Mass
2. Temperature
3. Position in a galaxy
Select the correct option from the codes given below:

Answer: [A] Only 1

The collapse of a star is a natural process that occurs when all stellar energy sources are exhausted.

If the mass of the collapsing part of the star is below a certain critical value, the end product is a compact star, either a white dwarf or a neutron star. But if the collapsing star has a mass exceeding this limit, the collapse will continue forever and form a black hole and astronomers believe that any collapsing star with solar mass above 0.7 will form a black hole.
