Which of the following paths could not be a real orbit for a planet around the Sun?
(a) Planet orbit shown as a slightly non-circular ellipse with the Sun at one focus. Minor axis is the same as other ellipses.
(b) Planet orbit shown as a moderately-flattened ellipse slightly wider than the others with the Sun at precise center of the ellipse. Minor axis is the same as other ellipses.
(c)Planet orbit shown as perfect circle with Sun at center. Radius is same as minor axis of elllipses.
(d) Planet orbit shown as a highly-flattened ellipse with the Sun at one focus. Minor axis is the same as other ellipses.
(e) Planet orbit shown as a moderately-flattened ellipse slightly wider than the others with the Sun at one focus. Minor axis is the same as other ellipses.
