Explanation:

While Kepler supported the Copernican model of the universe, Kepler concluded the following:
A. The circular orbits of the Copernican model weren't correct. Paths of the planets were elliptical.
B. The circular orbits of the Copernican model weren't correct. Paths of the planets were rectangular.
C. All other bodies in the universe move around the moon in triangular paths.
D. All other bodies in the universe move around the earth in circular paths.

Answers

Given the laws put forward by Kepler, we can conclude that option A is correct, he proved that the orbits of the planets were in fact elliptical.

Though options B and C are false due to the impossible nature of the shapes they describe for planetary orbits, option D is also false but is something that many astronomers once believed. It wasn't until the Kepler observations that this theory was proven to be false.

Kepler believed in the Copernican model of the universe, in which the planets revolved around the sun, but through measuring and observing the movement of mars, he would come to the realization that the orbits of the planets were in fact not circular as he and many other believed, but rather elliptical in nature.
