(C) The voltage gain $({A_v})$ of an amplifier is given by the formula:$|{A_v}| = \frac{\mu}{{1 + \frac{{{r_p}}}{{{R_L}}}}}$where $\mu$ is the amplification factor,${r_p}$ is the plate resistance,and ${R_L}$ is the load resistance.As the load resistance ${R_L}$ increases,the term $\frac{{{r_p}}}{{{R_L}}}$ decreases.Consequently,the denominator $({1 + \frac{{{r_p}}}{{{R_L}}}})$ decreases,which causes the voltage gain $|{A_v}|$ to increase.As ${R_L}$ approaches infinity,the term $\frac{{{r_p}}}{{{R_L}}}$ approaches zero,and the voltage gain $|{A_v}|$ approaches its maximum theoretical value of $\mu$.This behavior corresponds to a curve that starts from zero and asymptotically approaches the value $\mu$ as ${R_L}$ increases.Therefore,the correct curve is represented by option $(c)$.

The correct curve between voltage gain $({A_v})$ and load resistance $({R_L})$ is
