The Bode plot of a transfer function $G(s)$ is shown in the figure below.

The gain ($20$ log|$G(s)$| ) is $32$ $dB$ and –$8$ $dB$ at $1$ rad/s and $10$ rad/s respectively. The phase is
negative for all $ω$. Then $G(s)$ is

1.  $\frac{39.8}{s}$
2.  $\frac{39.8}{s^2}$
3.  $\frac{32}{s}$
4.  $\frac{32}{s^2}$
