In a common emitter configuration with suitable bias, it is given that `R_(L)` is the load resistance and `R_(BE)` is small signal dynamic resistance (input side). Then, voltage gain, current gain and power gain are given , respectively, by :
`beta` is current gain , `I_(B), I_(C)` and `I_(E)` are respectively base, collector and emitter currents.

Options

A. Option1 `beta^(2) (R_(L))/(R_(BE)), (DeltaI_(C))/(DeltaI_(B)), beta^(2) (R_(L))/(R_(BE))`
B. Option2 `beta^(2) (R_(L))/(R_(BE)), (DeltaI_(C))/(DeltaI_(E)), beta^(2) (R_(L))/(R_(BE))`
C. Option3 `beta (R_(L))/(R_(BE)), (DeltaI_(E))/(DeltaI_(B)), beta^(2) (R_(L))/(R_(BE))`
D. Option4 `beta (R_(L))/(R_(BE)), (DeltaI_(C))/(DeltaI_(B)), beta^(2) (R_(L))/(R_(BE))`
