Best ResponseYou've already chosen the best response.0Notice the words "ordered `pairs`". Pairs should indicate what is going on. A pair of numbers is a group of `two numbers`. That should help us to narrow down our options quite a bit. Which options have groups of 2?

Best ResponseYou've already chosen the best response.0Hmm... Option A shows no groups, they're all just single elements. So that's no bueno. Option D shows groups of 3, that's not what we want.
