What Is the Relationship Between Neutron Stars and the Chandrasekhar

What is the relationship between neutron stars and the Chandrasekhar limit?

A) The Chandrasekhar limit is an upper-mass limit for the stability of any massive system;it applies to any system,no matter how it was formed,including neutron stars.
B) The Chandrasekhar limit applies only to systems stabilized by degenerate electrons;neutron stars are stabilized by the pressure of the neutron degeneracy.
C) The Chandrasekhar limit applies specifically to the neutron degeneracy and thus to neutron stars.
D) The Chandrasekhar limit applies to radius,not mass.Thus,as long as a neutron star is big enough,it will not be affected by the Chandrasekhar limit.
