In the circuit shown, the symbols have their usual meanings. The cell has emf `varepsilon.X` is initially joined to `Y` for a long time. Then `X` is joined to `Z`. The maximum charge on `C` at any later time will be
A. `(varepsilon)/(Rsqrt(LC))`
B. `(varepsilonR)/(2sqrt(LC))`
C. `(varepsilonsqrt(LC))/(2R)`
D. `(varepsilonsqrt(LC))/(R)`
