Which option gives the correct pair of person and contribution?

Answer and explanation

Correct answer: Babbage and Analytical Engine

The direct answer is A: Charles Babbage and the Analytical Engine. Babbage designed the Analytical Engine, a proposed mechanical general-purpose calculating machine. It was not completed in his lifetime, but its planned parts, including a processing unit and memory, influenced the idea of modern computers. Option A is therefore the correct person-contribution pair. Option B is wrong because Pascal is associated with the Pascaline mechanical calculator, not the World Wide Web; the Web is associated with Tim Berners-Lee. Option C is wrong because Herman Hollerith is associated with punched-card data processing, not the Linux kernel. Option D is wrong because Alan Turing contributed to theoretical computing and codebreaking, not floppy-disk manufacturing. The method is to match each person with the contribution for which history commonly remembers them. Memory cue: Babbage built the idea of an analytical machine; Lovelace wrote an early algorithm for it.
