The answer is A; The universe was seen as heliocentered which means that everything revolved around the sun.
Before we knew the sun was at the center, everyone accepted Ptolemy's idea; the Earth was at the center of the universe and everything revolved around it
Galileo challenged this, but, the church, which was powerful at the time, shut him down and forced him to stop.
Later on, during the revolution, they realised he was right and that the sun was at the center of the universe.
