Answer:
Your answer is c!
Step-by-step explanation:
Galileo believed in the heliocentric theory, the theory that the Sun was the center, which was first discovered by Nicolaus Copernicus. The catholic church didn't like this theory because the holy scriptures mentioned that the Earth was at the center and not the Sun, so the catholic church sentanced this as heresy. Galileo proved this theory by his observations of the planet Venus. Just like our Moon, Venus goes through phases, which was enough proof of the Sun being the center.
