Explanation:

White dwarfs are one of the densest forms of matter, surpassed only by neutron stars and black holes. So, 1 is wrong.
A low or medium mass star (with mass less than about 8 times the mass of our Sun) will become a white dwarf. Stars that have a lot of mass may end their lives as black holes or neutron stars. So, 3 is wrong.
White dwarfs can tell us about the age of the Universe. If we can estimate the time it takes for a white dwarf to cool into a black dwarf, that would give us a lower limit on the age of the Universe and our galaxy. So, 2 is correct.
