In acommonemitter (CE) amplifier having a voltage gain G, the transistor used has transconductance 0.03 mho and current gain 25. If the abovetransistor is replaced with another one with transconductance 0.02 mho and current gain 20, the voltage gain will be:

A

$$\frac{5}{4}$$ G

B

$$\frac{2}{3}$$ G

C

1.5 G

D

$$\frac{1}{3}$$ G
