A series LCR circuit containing $5.0\text{H}$ inductor, $80\mu \text{F}$ capacitor and $40\Omega$ resistor is connected to $230\text{V}$ variable frequency ac source. The angular frequencies of the source at which power transferred to the circuit is half the power at the resonant angular frequency are likely to be:

1. A
   $46\text{rad/s}$ and $54\text{rad/s}$
2. B
   $42\text{rad/s}$ and $58\text{rad/s}$
3. C
   $25\text{rad/s}$ and $75\text{rad/s}$
4. D
   $50\text{rad/s}$ and $25\text{rad/s}$
