The correct reason why early astronomers incorrectly placed Earth at the center of their model of the Solar System is:
Because objects in the sky appeared to circle Earth.
Early astronomers observed the movements of celestial bodies such as the Sun, Moon, stars, and planets and noticed that they appeared to move in circular paths around the Earth. This geocentric model was based on observational evidence with the naked eye and the lack of knowledge about the actual layout of the Solar System. Other options, such as the idea that Earth was the largest object or that telescopes provided evidence for a geocentric model, do not accurately reflect the reasoning used by early astronomers. Additionally, they did not have accurate measurements of distances of celestial bodies at that time.
