Two students are trying to combine their decks of Battleémon cards (a knock off version of another famous card game) so that they make one large deck of cards that contains exactly one of each unique type of Battleémon card that they own - in alphabetical order.

Which of the following code segments below would correctly create combinedDeck based on the above specifications?

combinedDeck ← Add(deck1, deck2) combinedDeck ← RemoveDups(combinedDeck) combinedDeck ← Alphabetize(combinedDeck)
