KAPLAN OFFICIAL EXPLANATION:
You may notice a problem with this sentence right off the bat: It doesn't make sense for the officials to have given the dogs to pet sanctuaries and to have exterminated them as part of the same gesture. A sanctuary doesn't kill dogs, at least not if it really deserves to be called a sanctuary, so the sentence needs to describe the two actions (distributing the dogs to shelters and killing them) as alternatives. Choices (C) and (D) make that correction by substituting the original and with the much more logical or. Try reading the remaining options into the sentence and you'll see that (D) makes no sense in context; made collected is not anyone's idea of correct grammar. (C) remains.
