I found this from Manattan GMAT forum:
choice b features a rather strange-looking usage of a very common construction: the use of an appositive phrase (a noun phrase with no introductory words) to define a term, in this case 'social wasps'.
here's an example:
seamen distinguish flotsam, goods floating on seawater after a shipwreck from jetsam, goods thrown overboard by the crew of a ship.
you've probably seen this construction many times. it's weird-looking in this problem, though, because of the apparent repetition of 'wasps'.
but here's the story: the term being defined is 'social wasps'.
therefore, there's actually no redundancy: you need to think about 'wasps' and 'social wasps' as two completely different words. once you think about it that way, the sentence is just like the flotsam/jetsam example above, which should be noncontroversial.
