The open-loop transfer function of a control system with a negative unity feedback is as follows:

Which one of the following choices is a good approximation for the open-loop transfer function?

1) \(\widetilde{G}(s)=\frac{1}{s(s+10)}\)
2) \(\widetilde{G}(s)=\frac{10}{s(s+1)}\)
3) \(\widetilde{G}(s)=\frac{10}{s(s+10)}\)
4) \(\widetilde{G}(s)=\frac{1}{s(s+1)}\)
