For a narrow base PNP BJT , the excess minority carrier concentrations($\Delta n_{E}$ for emitter,$\Delta  p_{B}$ for base ,$\Delta n_{c}$ for collector) normalized to equilibrium minority carrier concentrations($n_{E0}$ for emitter, , $\Delta p_{B0}$ for base ,$\Delta n_{C0}$ for collector) in the quasi-neutral emitter,base and collector regions are shown below. Which one of the following biasing modes is the transistor operating in?

  1. Forward active
  2. Satiration
  3. Inverse active
  4. Cutoff
