(D) The cut-off grid voltage is defined as the negative grid bias voltage at which the plate current $(I_P)$ becomes zero. Looking at the provided mutual characteristic curve,the plate current $I_P$ is plotted against the grid voltage $V_g$ (represented as $V_a$ on the negative axis). At point $P$,the curve intersects the horizontal axis where $I_P = 0$. Therefore,point $P$ represents the cut-off grid voltage.

The point representing the cut-off grid voltage on the mutual characteristic of a triode is:
