The figure represents variation of triode parameter $(\mu$ or $r_{p}$ or $g_{m})$ with the plate current. The correct variation of $\mu$ and $r_{p}$ are given, respectively by the curves

(c) $r_{p}$ varies with $i_{p}$ according to relation $r_{p} \propto r_{p}^{- 1/3},i.e.,$ when $i_{p}$ increases, $r_{p}$ decreases, hence graph $C$ represents the variation of $r_{p}$
$\mu$ doesn’t depend upon $i_{p}$, hence graph $A$ is correct
