Answer 1

The answer to the question is B

Answer 2

Option B, It is the result of the core collapse of a low-mass star that sheds its outer layers.

Step-by-step explanation:

Stars which reaches the end of their evolution process becomes a white dwarf. The diameter of white dwarf is 0.01 times the diameter of sun but their masses are equivalent to each other. Stars at the stage of white dwarf are short of fuel as they have burned up its entire hydrogen. This leads to slowing down of fusion process followed by collapsing of stars on their own.

hence, only option B is correct
