In an LCR circuit as shown below both switches are open initially. Now switch `S_(1)` kept open. (q is charge on the capacitor and `tau = RC` is Capacitive time constant). Which of the following statement is correct?
A. Work done by the battery is half of the energy dissipated in the resistor
B. At `t=tau,q=CV//2`
C. At `t=2tau,q=CV(1-e^(-2))`
D. At `t=(tau)/(2),q=CV(1-e^(-1))`
