C. Copernicus developed his hypothesis in response to Ptolemy's hypothesis about planetary rotation, a hypothesis he found unsatisfying.
D. Copernicus saw an unsatisfying explanation and formulated a testable way to understand the motion of the planets.

Copernicus focused on developing his idea of the universe, because he was not completely satisfied with what Ptolemy proposed some years before. For him, the idea that the earth was the center of the universe and that all the planets rotated around it, did not sound very convincing, so he decided to take the challenge of observing the world around in a more detailed way, which lead him to propose his hypothesis about the way in which the universe is distributed.
