The ratio of thermionic currents is $(I/I_{0})$ for a metal when the temperature is slowly increased from $T_{0}$ to $T$ as shown in figure. ($I$ and $I_{0}$ are currents at $T$ and respectively). Then which one is correct

(a) $i \propto T^{2} \Rightarrow \frac{i}{i_{0}} = \left( \frac{T}{T_{0}} \right)^{2}$
This is the equation of a parabola
