A common emitter amplifier provides:

A common emitter amplifier is well-known in the field of electronics for providing significant voltage gain. When you consider the characteristics of different amplifier configurations, the common emitter stands out as one that effectively amplifies the input signal.

In a common emitter configuration, the output is taken across the collector with respect to ground, while the input is applied between the base and the emitter. This arrangement allows for a high voltage gain because the small changes in input voltage at the base lead to larger changes in output voltage at the collector, owing to how the transistor operates in this configuration.

In contrast, the common collector (or emitter follower) configuration is designed more for impedance matching rather than gain. It does not provide a significant output voltage swing, which results in lower voltage gain compared to the common emitter configuration.

Thus, when assessing the gain capabilities, it becomes clear that a common emitter amplifier indeed provides more voltage gain than a common collector, affirming the correctness of the selected answer.
