QUESTION 3 Why is there a mass limit for white dwarfs?

a "The mass limit is a consequence from the quantum nature of elections.

b If there was no mass limit, then some electrons would have to move faster than light which is impossible." c"The mass limit for white dwarfs comes from the fact that there is a mass limit for stars, and white dwarfs are formed from the death of some of these stars"

d The mass limit is a result of the geometrical nature of gravity "If the mass of the white dwarf is too great, then the electrons get closer to each other and attract with each other via the strong nuclear force, which forces the white dwarf to collapse"

e There is no mass limit
