A system's open-loop transfer function is given by \(G\left( s \right) = \frac{K}{{s\left( {s + 2} \right)\left( {s + 4} \right)}}\). If the system is having a unity negative feedback, which of the following is true for such a system to be stable?

1.	A system's open-loop transfer function is given by \(G\left( s \right) = \frac{K}{{s\left( {s + 2} \right)\left( {s + 4} \right)}}\). If the system is having a unity negative feedback, which of the following is true for such a system to be stable?
A.	K > 0
B.	0 < K < 24
C.	K < 24
D.	None of the above
Answer» C. K < 24
