A) a greater voltage applied to an emitter input can cause reverse breakdown of the E-B junction Of Q1.
B) a greater voltage applied to a base can cause a reverse breakdown of the B-C junction.
C) a greater voltage applied to a collector can cause a reverse breakdown of the B-C junction.
D) a greater voltage applied to a base input can cause reverse breakdown of the E-B junction Of Q1.
