A transformer on no-load is switched on to a source of voltage. It will draw a current which

A)     The same as the steady-state magnetizing current
B)      Several times the steady-state magnetizing current depending upon the initial state of the residual flux in the transformer core
C)      Several times the steady-state magnetizing current depending upon the initial state of the residual flux in the transformer core
D)     Twice the steady-state magnetizing current provided the core has no residual flux
