What is the relation between half life ($t_{1/2}$) and temperature for an $n^{th}$ order reaction ;$n > 2$

Question

$\begin{array}{1 1}(a)\;ln \;t_{1/2}=ln\; A'+\large\frac{2E_a}{RT}\\(b)\;ln\;t_{1/2}=ln\;A'+\large\frac{E_a}{RT}\\(c)\;ln\;t_{1/2}=ln \;A'-\large\frac{E_a}{RT}\\(d)\;None\end{array}$
