D Correct answer
Explanation

In historical punch-card data processing, a 'Reproducer' was a machine that could duplicate punch cards and perform gang punching (creating multiple cards with identical data). A Sorter arranged cards, a Collator merged/merged card decks, and 'Dual card' is not a machine type. The Reproducer handled bulk card creation.
