Hubble's Law tells us that the velocity at which a galaxy is receding from us is proportional to its distance from us. In other words, the farther away a galaxy is, the faster it appears to be moving away. Hence:
**You can calculate the velocity of a galaxy as it travels away from us, and, with some additional calculations, infer its distance.**
Therefore, the most accurate choice from your options may be interpreted as:
**You can calculate the distance to any galaxy in the Universe simply by measuring its velocity.**
Note that this is more of an inference since the law allows for determining distances given the velocity of a galaxy—akin to what Hubble's Law provides.
