A capacitor C is fully charged with voltage  $V_0$. After disconnecting the voltage source, it is connected in parallel with another uncharged capacitor of capacitance $\frac{C}{2}$ . The energy loss in the process after the charge is distributed between the two capacitors is:

• A

  $\frac{1}{2}C{V}_0^2$

• B

  $\frac{1}{3}C{V}_0^2$

• C

  $\frac{1}{6}C{V}_0^2$

• D

  $\frac{1}{4}C{V}_0^2$
