The correct Answer is A$,$ need help on the work to come to this solution

For a system described by the transfer function

$H(s)=\frac{7s^5+13s^4+321s^3+4s^2+31s+17}{s^6+19s^5+42s^4+741s^3+444s^2+31s+2}$

assuming all initial conditions are zero, what is the $C$ matrix in the Reachable Canonical form?

$($a$)$

$C=\left[\begin{array}{cccccc}17& 31& 4& 321& 13& 7\end{array}\right]$

$($b$)$

$[$:$C={\left[\begin{array}{cccc}-7& -13& -321& -4\end{array}\right]}^{-31},-17$
