For amplification by a triode, the signal to be amplified is given to (a) the cathode (b) the grid (c) the glass envelope (d) the anode

Answer: (b). The grid is close to the cathode, so a small change in grid voltage causes a large change in plate current. That is why the input signal is applied between grid and cathode, and the amplified output is taken from the plate circuit. So the answer is (b) the grid.
