What is the stability factor against VBE for the collector feedback configuration?

What is the stability factor against VBE for the collector feedback configuration? Correct Answer β/(RB + Rc * (1 + β))

This is easily derived from the Collector feedback configuration by using the method of K.V.L. deriving a relation between the collector current and the base emitter voltage. It should be noted that the stability against VBE increases in comparison to the base bias comparison.
