(D) $p-n$ junction diode acts as a rectifier. When the input signal is positive $(+5 \,V)$, the diode is in forward bias and conducts current, allowing the signal to appear across the load resistor $R_L$. When the input signal is negative $(-5 \,V)$, the diode is in reverse bias and acts as an open circuit, blocking the current. Therefore, the output across $R_L$ will only show the positive half of the input signal, resulting in a square wave with a peak at $5 \,V$ and $0 \,V$ during the negative cycle.

If in a $p-n$ junction diode, a square input signal of $5 \,V$ to $-5 \,V$ is applied as shown, then the output signal across $R_L$ will be:
