The input-output transfer of a plant $\mathit{H}\left(\mathit{s}\right)=\frac{100}{\mathit{s}\left(\mathit{s}+10\right){}^2}.$The plant is placed in a unity negative feedback configuration as shown in the figure below.

The signal flow graph that DOES NOT model the plant transfer function  $\mathit{H}\left(\mathit{s}\right)=\frac{100}{\mathit{s}\left(\mathit{s}+10\right){}^2}$ is:
