An n-p-n transistor in a common-emitter mode is used as a simple voltage-amplifier with a collector current of 4 mA. The terminals of a 8 V battery is connected to the collector through a load-resistance `R_L` and to the base through a resistance `R_B`. The collector-emitter voltage `V_(CE)=4V`, the base-emitter voltage `V_(BE) = 0.6 V` and the current amplification factor `beta_(dc) = 100`. Then

A

`R_(L)=1k Omega , R_(B) = 185 kOmega`

B

`R_(L) = 2kOmega , R_(B) =150 k Omega `

C

`R_(L) = 1 k Omega ,R_(B) =240 kOmega `

D

`R_(L) = 3k Omega , R_(B )=185 kOmega`
