Do We Know Whether or Not the Dark Matter in the Milky

Do we know whether or not the dark matter in the Milky Way is made up of planets,white dwarfs,neutron stars,and black holes?

A) We are not sure;they could make up much of the dark matter.
B) We observe no emission from these objects;therefore they cannot make up much of the dark matter.
C) Searches for gravitational lensing that such objects would produce found very few examples;therefore they cannot make up much of the dark matter.
D) Calculations of the chemical enrichment such objects would produce suggest the halo could be enriched by them;therefore they could make up most of the dark matter.
