In 1543, published his views of earth and other planets revolving around the sun.
a. kepler
c. copernicus
b. magellan
d. galileo

I believe the answer is: C. Copernicus

At that time, most people believe that earth is the center of the universe due to the teachings that were spread by the church. Copernicus at that time stated that The Sun is the center of the universe, not the earth. Since the church at that time had a really strong influence within the government, his view caused him a lot of troubles.

i see, would you mind putting it as one?
