Answer:
The correct answer option is A) Ellipse.
Explanation:
A curve in a plane which is surrounded by the two focal points such that the sum of the distances between the two focal points is constant for each of the points on the curve, is called an ellipse.
The planets in the space around the sun follow an elliptical path, with the Sun at one focus so the sum of the distances between the planets and the Sun remain the same.
