A. An FET that exhibits a current flow between source and drain when no gate voltage is applied
B. An FET that has no current flow between source and drain when no gate voltage is applied
C. An FET that exhibits very high electron mobility due to a lack of holes in the N-type material
D. An FET for which holes are the majority carriers
