Dear
GMATNinja,
I understood how the answer is option B.
But while answering I ended up eliminating the options that changed "shellfish" to "seafood"?
Does GMAT allow us to change the words??
Sorry for the delay!
This is in fact an official question (though it is fairly old -- from the 12th Edition Official Guide), and "seafood" is not a typo.
One thing to remember is that there is nothing special about choice (A), and we are not confined to the meaning/wording/etc. that we find in the first option. So (B) doesn't really "change" the intended meaning, exactly -- it just offers a different word option. And since there's nothing inherently
wrong with the use of "seafood" in (B), we have to look for other decision points.
That said, it does seem a bit odd that they used two different words for no good reason at all. Maybe that's why they've retired this one?
