Explanation:
Option C: Charles Babbage
The British scientist Charles Babbage, the father of computers, thought too. Babbage wanted to build a machine that could perform accurate calculations quickly to avoid errors in navigation and engineering. This is when he came up with the design for the first computer called the Difference Engine in 1822.
