感应电动势包括感生电动势和动生电动势，下列说法哪个是正确的？ Induction Electromotive Force includes Induced Electromotive Force and Motional Electromotive Force, which of the following statements is true？

A、由于磁场变而产生的电动势不是感生电动势； The electromotive force due to the change of magnetic field is not Induced Electromotive Force;

B、由于线圈（导体）动产生的电动势是动生电动势； The electromotive force produced by the coil (conductor) is Motional Electromotive Force.

C、由于磁场变而产生的电动势是动生电动势； The electromotive force due to the change of magnetic field is Motional Electromotive Force.

D、由于线圈（导体）动产生的电动势不是动生电动势； The electromotive force due to coil (conductor) motion is not Motional Electromotive Force;
