Question

Explanation:

Kepler's First Law states that planets move in elliptical orbits around the sun, with the sun located at one of the foci of the ellipse. Options a and b are incorrect as they do not reflect the actual orbital shape described by the law.

Answer:

C. Planets move in elliptical orbits with the sun at one focus.
