Solution

The correct option is A Emitter is connected to negative terminal of a battery.
If a p-n-p transistor is to be used as an amplifier in common emitter mode, base-emitter must be biased forward. So, base should be connected with the positive terminal of the battery whereas emitter should be connected with the negative terminal of the battery.
