Which astronomer is especially associated with observational evidence that distant galaxies are receding, supporting the expansion of the universe?

Answer and explanation

Correct answer: Edwin Hubble

Edwin Hubble is especially associated with observations relating galaxy distances to their recession speeds, which supported the idea that the universe is expanding. Earlier redshift observations by other astronomers also contributed, so Hubble should not be taken as the sole source of all such evidence. Option B is the best answer.
