In an LCR circuit as shown below both switches are open initially. Now switch `S_(1)` is closed and `S_(2)` kept open. (q is charge on the capacitor and `tau = RC` is Capacitive time constant). Which of the following statement is correct?

A

`At" "t = tau, q= CV//2`

B

`At" "t=2tau, q=CV(1-e^(-2))`

C

`At" "t=(tau)/(2), q=CV(1-e^(-1))`

D
