Best answer
The correct option is (b) OHM

The best explanation: hie = vBE/ib; common emitter input impedance

                           For VCE = 0   i.e. output short circuited

Where vBE = Base emitter voltage   i.e. input voltage

               ib =  Base current  i.e. input current

  We know that V/I = R. Its unit is ohm.
