What principle was copernicus unable to provide evidence against? oa) uniform circular motion )heliocentric universe c) geocentric universe d) retrograde motion

Corpenicus was unable to provide evidence against the heliocentric universe.

Explanation:

The geocentric theory, according to which the Earth was the center of the Universe, remained fixed and the Sun, planets and stars revolved around it was challenged by Copernicus. He presented a very different theory, according to which the Earth is a planet and revolves with the others around the Sun. But Copernicus could not prove his theory, which he called heliocentric. This theory was demonstrated a century later by Galileo Galilei.
