A. Elliptical orbits cause a planet to sometimes be closer to and sometimes farther away from the Sun.

Explanation:

The astronomer Johannes Kepler refined the Copernicus' heliocentric theory with the introduction of elliptical orbits with the formulation of his three laws of planetary motion, finally explaining why planets orbited the Sun at different speeds at different times, because prior to this, the heliocentric model used only circular orbits.

In this sense, the fact that planetary planetary orbits are elliptical was told by Kepler in the first Law of Planetary motion that states:

The orbit of a planet around the Sun, is in the form of an ellipse with the Sun at one of the two foci of that ellipse.
