For the B) part, I don't get why is it that for calculating voltage between collector an the emitter (V_{ce}) I take into account diode on base (0.7V), whereas for part A) it's ignored?

Why is V_{ce}in part A and part B are calculated differently? Why is it that in part A voltage of 0.7V isn't taken into account? I get that if β_{f}= infinite, and β_{f}= i_{c}/i_{b}i_{b}-> 0
