Answer:
C. Observations and experimentations.
Explanation:
Medieval scientists, and consequently the beliefs of the Roman Catholic Church, which was one of the major powers during this time period, typically revolved around the fundamental ideology of geocentric theory, which establishes through the historical representation and visual representation, that the Earth is in the center of the universe, and everything else revolves around her. Galileo Galilei, on the other hand, believed in the heliocentric theory, in basing his observations of Venus, which in being observable like Earth's moon, can be seen to have phases. The phases also correspond with Earth's phases of Night and Day, which backed his ideal of heliocentrism.
It is important to note that while the Catholic Church had applied the geocentric theory on the basis of the Bible (an appeal to authority), the bible itself does not cement that the Earth is in the center of the universe. Simply put, the author of books that describe the Earth as seemingly in the center of the universe is simply applying their own observations, rather than stating a fact. It is therefore, applicable that the sun rises and sets to the observable eye, therefore denoting the writing of such in the Holy Bible, but does not imply that the Earth in itself is the original center of the universe. It is also important to note that the suppression of Galileo is not so much of the reasoning of the heliocentric theory, but the contrast to the dominant Catholic Church. The Catholic Church feared that all beliefs that the Catholic Church upheld would be questioned if some of the beliefs held by the Church is proven to be false, and so sought to silence Galileo.
