-What functions do D1 and D2 serve in Figure 15- 1?

A) D1 clamps the input of Q1 to prevent saturation, and D2 prevents reverse voltage spikes from damaging Q4.
B) D1 and D2 are both steering diodes which are used to ensure that the input current is correctly steered to the proper output terminal.
C) D1 provides a return path for the emitter current of Q1, and D2 prevents reverse voltage from being applied to Q3.
D) D1 prevents negative spikes from damaging Q1, and D2 ensures that Q4 will be off when Q2 is on.
