The figure shows elliptical orbit of a planet \( \mathrm{m} \) about the sun S. The shaded area SCD is twice the shaded area SAB. If \( t_{1} \) is the time for the planet to move from \( \mathrm{C} \) to \( \mathrm{D} \) and \( \mathrm{t}_{2} \) is the time to move from A to B then
(a) \( t_{1}=4 t_{2} \)
(b) \( t_{1}=2 t_{2} \)
(c) \( \mathrm{t}_{1}=\mathrm{t}_{2} \)
(d) \( \mathrm{t}_{1}\mathrm{t}_{2} \)
