$${{10\left( {s + 5} \right)} \over {s\left( {s + 2} \right)\left( {s + 25} \right)}}$$
B
$${{1000\left( {s + 5} \right)} \over {{s^2}\left( {s + 2} \right)\left( {s + 25} \right)}}$$
C
$${{100\left( {s + 5} \right)} \over {s\left( {s + 2} \right)\left( {s + 25} \right)}}$$
D
$${{80\left( {s + 5} \right)} \over {{s^2}\left( {s + 2} \right)\left( {s + 25} \right)}}$$
