Three uncharged capacitors of capacitance \( C_{1}, C_{2} \) and \(...

Three uncharged capacitors of capacitance \( C_{1}, C_{2} \) and \( C_{3} \) are connected to one another as shown in figure. The potential at \( O \) will be
(a) \( 3 \mathrm{~V} \)
(b) \( \frac{49}{11} \mathrm{~V} \)
(c) \( 4 \mathrm{~V} \)
(d) \( \frac{3}{11} \mathrm{~V} \)
