A

the current and `P.d` across the resistance lead `P.d` across the inductance by `pi//2`

B

the current and `P.d` acorss the resistance lags behind the `P.d` across the inductance by angle `pi//2`

C

The currentd across resistance leads and the `P.d` across resistance lags behind the `P.d` across the inductance by `pi//2`

D

the current across resistance lags behind and the `P.d` across the resistance leads the `P.d` across the inductance by `pi//2`
