Consider the push$-$pull stage shown below. Determine the bias current of Q$1$ andQ$2$ so as to obtain a voltage gain of $0\mathrm{.}7$ with RL $=8.$ Neglect the incremental resistance of D$1$ and D$2.$

Select one:

a$.,7\mathrm{.}58mA$

b$.$ None of these

c$.,5\mathrm{.}58mA$

d$.3\mathrm{.}58$ mA
