The Correct Option is B

Solution and Explanation

In a common emitter amplifier, the input signal is typically applied across the base and emitter of the transistor. The current passing through the transistor is found to be 2A.

Step 2: Conclusion.
The input signal in a common emitter amplifier is applied across \( 2 \, \text{A} \), corresponding to option (b).
