A
Kepler
B
Magellan
C
Copernicus
D
Galileo
Explanation: 

Detailed explanation-1: -Copernican heliocentrism is the astronomical model developed by Nicolaus Copernicus and published in 1543. This model positioned the Sun at the center of the Universe, motionless, with Earth and the other planets orbiting around it in circular paths, modified by epicycles, and at uniform speeds.

Detailed explanation-2: -The majority of people believed that Earth was the center of the universe and that all other celestial bodies were perfect and revolved around it. However, Copernicus had proposed a Sun-centered system, which Galileo instinctively believed was correct.

Detailed explanation-3: -Nicolaus Copernicus in his De revolutionibus orbium coelestium ("On the revolution of heavenly spheres", first printed in 1543 in Nuremberg), presented a discussion of a heliocentric model of the universe in much the same way as Ptolemy in the 2nd century had presented his geocentric model in his Almagest.
