high frequency slope

Consider a stable system with transfer function $$$G\left(s\right)=\frac{s^p+b_1s^{p-1}+....+b_p}{s^q+a_1s^{q-1}+....+a_q}$$$ Where $$b_1,.......,b_p$$ and $$a_1,.......,a_q$$ are...

In a Bode magnitude plot, which one of the following slopes would be exhibited at high frequencies by a 4 th order all-pole system?
