The correct answer to this open question is the following.
Although there are no options attached we can say the following.
We are talking about the great Galileo.
The Italian physicist, mathematician, and astronomer who invented an accurate telescope and supported Copernicus's ideas, was Galileo Galilei.
Galileo (15641642) was an Italian astronomer that established the foundation of further astronomical and physicist studies in the modern world.
He agreed with many ideas established by scientist Copernico that helped him to develop his invention: the telescope.
He wrote interesting documents such as "In Motion," and "The Little Balance," that made the Catholic Church accuse him of heresy. Galileo had to retract from those ideas to avoid being burnt in the stakes.
