(C) The input current $i_i$ is given by $i_i = \frac{V_i}{R_i}$,where $V_i = 100 \ mV = 0.1 \ V$ and $R_i = 2000 \ \Omega$.$i_i = \frac{0.1}{2000} = 5 \times 10^{-5} \ A$.The output current $i_o$ is given by $i_o = \beta \times i_i$.$i_o = 50 \times 5 \times 10^{-5} = 250 \times 10^{-5} = 2.5 \times 10^{-3} \ A$.The output voltage $V_o$ is given by $V_o = i_o \times R_o$,where $R_o = 5000 \ \Omega$.$V_o = 2.5 \times 10^{-3} \times 5000 = 12.5 \ V$.Thus,the peak value of the output voltage is $12.5 \ V$.
