The correct option is A Copernicus
"The
earth revolves rounds the Sun not the Sun revolves rounds the Earth." This conclusion was
made by Copernicus. He was an astronomer of Poland. He is still considered as
the father of the modern astronomy. Copernicus concluded from his studies that
every planet, including Earth, revolved around the Sun. He also determined that
the Earth rotates daily on its axis. At that time, Copernicus did not have any
tools to prove his theories. Later, astronomers such as Galileo proved that he
was correct.
