The correct answer is:
infinite quantity
Key Idea Change in current at saturation is
zero.
We know that plate resistance is given by
$$
r_{p}=\frac{\delta V}{\delta I}
$$
where $\delta V$ is change in voltage and $\delta I$ is change in current. Also, at saturation change in current is zero.
$\therefore$
$$
r_{p}=\frac{\delta V}{0}=\infty
$$
Hence, plate resistance will be infinite.
