Which capacitor gets the larger voltage?

Initially uncharged ideal 3 μF and 6 μF capacitors are connected in series across a 12 V ideal battery. The junction between them is isolated and initially neutral.

After charging, what is the voltage magnitude across the 3 μF capacitor?

Organize the givens & assumptions

Capacitances: 3 μF and 6 μF
Battery voltage: 12 V

Ideal lumped capacitors with no leakage; electrostatic final state. The central junction has no external connection or initial net charge.

A $4\ \mathrm{V}$
B $6\ \mathrm{V}$
C $8\ \mathrm{V}$
D $12\ \mathrm{V}$
