B Correct answer
Explanation

A tunnel or Esaki diode is much more heavily doped than a normal p-n junction diode - typically about 1000 times higher doping concentration. This heavy doping creates a very narrow depletion region that allows electrons to tunnel through, creating the negative resistance characteristic that makes tunnel diodes useful in high-frequency oscillator circuits.
