Which of the following is true about n-channel E-MOSFET?(a) Electrons

1.	Which of the following is true about n-channel E-MOSFET?(a) Electrons are the majority charge carries(b) Holes are the majority charge carries(c) Both holes and electrons are present in same ratio(d) Neutrons are the charge carriersI got this question during a job interview.My question comes from The Insulated-Gate FET(MOSFET) in section Field-Effect Transistors of Electronic Devices & Circuits
Answer» The correct option is (a) Electrons are the MAJORITY charge carries Explanation: n-channel E-MOSFETis designed in such a way that the source and DRAIN are formed by the n-type impurity which CONTAINS electrons as the majority charge carriers. The doping concentration of source and drain is slightly more than the GATE and body, and thus the channel created is by electrons of a source and drain.
