11. According to Hubble's Law the velocity of v of a galaxy moving away from Earth is proportional to its distance from Earth. Consider two galaxies one of which is twice as far away as the other from Earth at some instant of time. At subsequent times, the ratio of their distances to Earth will be:
(A) 2 to 1.
(B) greater than 2 to 1.
(C) less than 2 to 1.
(D) it depends on the specific time.
(E) it depends on the positions of galaxies.
