The early computer concept/technology developed by Allied codebreakers to crack Enigma?

• A. Turing Machine
• B. Colossus
• C. ENIAC
• D. Z3

Answer: (A)

The main idea here is that computation theory provided the blueprint for automating how to solve the Enigma puzzle. The Turing Machine is the abstract model Alan Turing introduced for a machine that can follow a set of rules to manipulate symbols on a tape, illustrating that a single, general-purpose process could execute any computable task given the right program. That conceptual framework underpinned the design of automated decoding devices used at places like Bletchley Park to test Enigma settings quickly and systematically. While the actual apparatus used to crack Enigma was a practical machine built from these ideas—the Bombe—the Turing Machine embodies the fundamental thinking about how to mechanize complex problem solving. The other options don’t fit as well: Colossus targeted the Lorenz cipher, not Enigma, and ENIAC and Z3 were early computers not specifically tied to Enigma cryptanalysis.
