The figure shows the motion of a planet around the sun in an elliptical orbit with the sun at the focus. The shaded areas are equal. If $t_1$ and $t_2$ represent the time taken for the planet to move from $A$ to $B$ and $C$ to $D$ respectively,then:
- A$t_1 < t_2$
- B$t_1 > t_2$
- C$t_1 = t_2$
- DNone of the above
