A plant transfer function is given as $$G\left( s \right) = \left( {{K_P} + \frac{{{K_I}}}{s}} \right)\left( {\frac{1}{{s\left( {s + 2} \right)}}} \right).$$ When the plant operates in a unity feedback configuration, the condition for the stability of the closed loop system is
A. $${K_P} > \frac{{{K_I}}}{2} > 0$$
B. $$2{K_I} > {K_P} > 0$$
C. $$2{K_I} < {K_P}$$
D. $$2{K_I} > {K_P}$$
