The $\text{h}$-parameters of a two port network are shown below. The condition for the maximum small signal voltage gain $\frac{\mathrm{V}_{\text {out }}}{\mathrm{V}_{\mathrm{s}}}$ is
- $\mathrm{h}_{11}=0, \mathrm{~h}_{12}=0, \mathrm{~h}_{21}=$ very high and $\mathrm{h}_{22}=0$
- $\mathrm{h}_{11}=$ very high, $\mathrm{h}_{12}=0, \mathrm{~h}_{21}=$ very high and $\mathrm{h}_{22}=0$
- $\mathrm{h}_{11}=0, \mathrm{~h}_{12}=$ very high, $\mathrm{h}_{21}=$ very high and $\mathrm{h}_{22}=0$
- $\mathrm{h}_{11}=0, \mathrm{~h}_{12}=0, \mathrm{~h}_{21}=$ very high and $\mathrm{h}_{22}=$ very high
