The correct answer is In 1543, Nicolaus Copernicus published On the Revolution of the Celestial Spheres, which said the universe was heliocentric.

Explanation

Nicolás Copernicus (1473 - 1543) was an astronomer of Prussian origin who stands out for being the one who first formulated the heliocentric theory of the solar system. It is necessary to remember that during the medieval period (5th century BC - 15th century AD) science was stagnant due to the rise of the Christian religion in Europe. Later, with the arrival of the Renaissance and the Enlightenment, the sciences took on greater importance than religion and there were great technological, scientific, mathematical, geographical advances and in general in all areas of science. During this time the theory that had been accepted throughout the world was the Geocentric one that affirmed that the earth was the center of the solar system and that the other planets orbited around it. For his part, Nicolas Copernicus spent a long time studying to argue the Heliocentric theory, in which he rejected the claim that the planet Earth was the center of the solar system to propose that the sun was the center of the solar system and that the planets orbited around it. Copernicus's theory was unveiled the same year of his death

1543, when he published his book the Revolution of the Celestial Spheres, in which he exposed his model of the solar system and explained his theory in detail. Therefore, the correct answer is In 1543, Nicolaus Copernicus published On the Revolution of the Celestial Spheres, which said the universe was heliocentric.
