B Correct answer
Explanation

Hubble's Law states that galaxies are moving away from us at speeds proportional to their distance - more distant galaxies recede faster. This was key evidence for the expanding universe and Big Bang theory. Kepler's laws describe planetary motion, Huygens studied wave theory, and Friedmann developed cosmological models.
