I don't know how to calculate part C) of the question. I'm unsure what saturation of a transistor refers too.

If the base voltage is greater than the collector voltage, then it is saturated. The more collector current, the higher voltage drop across Rc, which lowers the collector voltage.

Ok. So the maximum value would occur when the collector voltage is 0.6V also. If that is the case:
  • The voltage across RC would be 11.4V
  • The current IC would be 11.4/1000 = 11.4 mA.
  • And with that , B would be (11.4 x 10-3)/(20 x 10-6) = 570
