How does DC input impedance on the gate of a field-effect transistor compare with the DC input impedance of a bipolar transistor?

SelectAnswer
AAn FET has high input impedance; a bipolar transistor has low input impedance
BThey cannot be compared without first knowing the supply voltage
CAn FET has low input impedance; a bipolar transistor has high input impedance
DThe input impedance of FETs and bipolar transistors is the same
