The correct answers are: The base-emitter junction is forward biased, The input signal is connected in series with the voltage applied to the base-emitter junction
The circuit of a CE amplifier is as Shown below.


This has been shown a NPN transistor. Therefore base emitter are forward, biased and input signal is connected between base and emitter.
