A has parallelism.. center of the milkyway and of...the

B. has a possesive noun.. i.e. an apostrophe and hence violates parallelism.. see it says a black hole lies at the Milky ways' center and of the .... but this sentence does not refer to center of 100 billion other galaxies..

Hope this helps.

The problem in B is that the second arm after the conjunction ‘and’ is just a dangling phrase without a working verb; even if you attach it to the earlier verb lies at, it doesn’t make sense.
