yeah, but:
* it doesn't say "THE home to...", it just says "home to..."
(this actually doesn't make any difference here; i'm just pointing it out)
* it's perfectly possible for several islands (or several of something else) to be "home to" something. i.e., if you have "X is/are home to...", then there is no guarantee that X is singular.
for instance:
these row houses, which were once home to the city's elite, are now home to a fearsome street gang.so - as i stated above, the
only thing wrong with this aspect of (b) is the weird subject shift that takes place.
i.e.
you can totally say that
the constellation of islands is home to X people, but you can also say that
the islands (themselves) are home to X people.
the former is
only better in that "the constellation..." is already the subject of the preceding clause, so that the sentence "flows" better.

on the other hand, the
pronoun in (a) ("it") is also better than the pronoun in (b) ("they").
in (a), "it" is technically ambiguous between "vast constellation" and "South Pacific", but there is GRAMMATICAL PARALLELISM between "it" and "vast constellation" because each of these is the subject of its respective clause. (
click here for more details on this "acceptable pronoun ambiguity".)
in (b), "they" is also technically ambiguous, between "small islands" and "a few million people". however, in this instance,
neither of these words is grammatically parallel to the pronoun: the pronoun is the subject of its clause, but neither of these possible antecedents is the subject of its own clause. so this is not as good.
