Best answer
The correct answer is (a) True

The explanation: From the equation IE = IC + IB, once the IE increases, the base current will reduce because of emitter feedback, resulting in a constant gain. In emitter feedback circuits, the resistance RE is used to provide negative feedback which is given to the base to maintain a constant gain.
