A) will give an approximate value for distant galaxies. Close galaxies can vary a lot from the Hubble relation because of local velocity differences. (Out nearest glaxy is actually getting closer and will eventually collide with the Milky Way!) By the way, Hubble's "Law" is not considered a law. It is an approximately linear relation between velocity and distance, based on a curve fit to scattered data.
C) is a good answer
G) would be OK is it just said "supernovae", but white dwarfs do not become supernovae
The other choices are nonsense.
