The emitter region in the p-n-p junction transistor is more heavily doped than the base region so that—

1. The flow across the base region will be mainly because of electron
2. The flow across the base region will be mainly because of holes
3. Recombination will be increased in the base region
4. Base current will be high

Correct Option: B
