In a BJT, which of the following layers is heavily doped?

In a BJT, which of the following layers is heavily doped? Correct Answer Emitter

The emitter is the most heavily doped and contains the maximum amount of charge carriers. It is the emitter’s task to inject carriers into the base. These bases are thin and lightly doped. For npn B JT, emitter injects electrons, and for pnp, it injects holes.
