The pole-zero plot is shown here when the DC gain is equal to 20. The system transfer function is . . . . . . . .

A. $$\frac{{33.33\left( {s - 3} \right)}}{{\left( {s + 1} \right)\left( {{s^2} + 4s + 5} \right)}}$$

B. $$\frac{{ - 33.33\left( {s + 3} \right)}}{{\left( {s + 1} \right)\left( {{s^2} + 4s + 5} \right)}}$$

C. $$\frac{{33.33\left( {s + 3} \right)}}{{\left( {s + 1} \right)\left( {{s^2} + 4s + 5} \right)}}$$

D. $$\frac{{33.33\left( {s + 3} \right)}}{{\left( {s - 1} \right)\left( {{s^2} + 4s + 5} \right)}}$$
