The forward transfer function $$G\left( s \right) = \frac{{20}}{{\left( {{s^3} + 2{s^2} + 4s} \right)}}$$ and the feedback gain H(s) = -0.8. Find the closed loop transfer function of the SFG.
A. $$\frac{{20s}}{{\left( {{s^3} + 2{s^2} + 4s + 16} \right)}}$$
B. $$\frac{{20}}{{\left( {{s^3} + 2{s^2} + 4s + 20} \right)}}$$
C. $$\frac{{20}}{{\left( {{s^3} + 2{s^2} + 4s + 16} \right)}}$$
D. $$\frac{{20s}}{{\left( {{s^3} + 2{s^2} + 4s + 20} \right)}}$$
