15. The figure shows a battery (30.0 V) and three (uncharged capacitors): C₁=12.0 µF, C₂= 4.00 μF, C₃=6.00 µF. The switch is first thrown to the left to charge C₁. Then the switch is thrown to the right to transfer charge to C₂ and C₃. When equilibrium is reached, what is the energy (J) stored in C₁?

(A) 3.75×10^-3,
(B) 2.52×10^-6,
(C) 5.89×10^-5,
(D) 9.60×10^-2,
(E) 1.04×10^-4.
