Which object forms when a supergiant runs out of fuel? a red giant a black hole a white dwarf a neutron star

The supergiant stars are considered as the biggest stars in the universe. They can be thousands of times larger than the Sun and can exhibit a mass up to 100 times more. In the case when the supergiants run out of fuel or hydrogen they give rise to a supernova, and then either turn into a black hole or a neutron star.  

A neutron star refers to a very dense but little star, comprising neutrons and emerges as the core of the dead supergiant.  

A black hole refers to a location in space, more accurately in time-space, which is most generally known for its drastic gravitational influence and for its dark color.  

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."

i think it's c. if you look search electronic symbol on google and then click on wiki it shows you a
