The figure above represents the orbit of a planet
around a star, S , and the marks divide the orbit
into 14 equal time intervals, t = T/14 , where T
is the orbital period. If the only force acting on
the planet is Newtonian gravitation, then true
statements about the situation include which of
the following?

I. Area A = area B

II. The star S is at one focus of an elliptically shaped orbit.

III. \( { T }^{ 2 }\quad =\quad C{ a }^{ 3 } \) , where a is the semi-major axis of the ellipse and C is a constant.
