An alternating e.m.f. of angular frequency \[\omega \] is applied across an inductance. The instantaneous power developed in the circuit has an angular frequency [Roorkee 1999]

• A.            \[\frac{\omega }{4}\]       
• B.            \[\frac{\omega }{2}\]
• C.            \[\omega \]                          
• D.            \[2\omega \]
