The open-loop transfer function of a plant is given as $$G(s) = {1 \over {{s^2} - 1}}.$$ If the plant is operated in a unity feedback configuration, then the lead compensator that can stabilize this control system is

$${{10\left( {s - 1} \right)} \over {s + 2}}$$

$${{10\left( {s + 4} \right)} \over {s + 2}}$$

$${{10\left( {s + 2} \right)} \over {s + 10}}$$

$${{2\left( {s + 2} \right)} \over {s + 10}}$$
