When `100`volts `DC` is applied across a coil, a current of `1amp` flows through it. When `100` volt `AC` at `50` cycles `s^(-1)

When `100`volts `DC` is applied across a coil, a current of `1amp` flows through it. When `100` volt `AC` at `50` cycles `s^(-1)` is applied to the same coil, only `0.5` ampere current follows.then the impedence of the coil is
A. `100 Omega`
B. `200 Omega`
C. `300 Omega`
D. `400 Omega`
