Best answer
Correct option is (a) Reduces the gain

To explain: Due to the negative feedback, the voltage gain will reduce drastically compared to other biasing techniques. Hence there will be a huge amount of power loss in the form of heat dissipated across emitter and collector. Setting Q- Point is also difficult for emitter feedback circuit.
