Graham Bell

The correct answer is (a) Galileo.

Galileo Galilei was an Italian astronomer, physicist, and engineer who made fundamental contributions to the sciences of motion, astronomy, and strength of materials and to the development of the scientific method. He also made revolutionary telescopic discoveries, including the four largest moons of Jupiter.

Gutenberg is credited with inventing the printing press, which revolutionized the way information was disseminated. Edison is credited with inventing the light bulb, the phonograph, and the motion picture camera. Bell is credited with inventing the telephone.

While each of these men made significant contributions to their respective fields, it was Galileo who invented the telescope.
