HURRY WILL MARK BRAINLIEST Farha makes the graphic organizer shown to review the characteristics of transistors. Which statement belongs in the region marked X?
A. The current flows away from the base.
B. The collector is more positive than either the base or the emitter.
C. It is made from three layers of semiconductors.
D. Its main charge carriers are positive holes.

C. It is made from three layers of semiconductors.

Explanation:

Bipolar transistors (pnp and npn) are usually made from a sandwich of three semiconductors layers. The main charge carriers are holes and electrons. An npn transistor has two semiconductor junctions that share a thin middle positively enhanced region (the material is enhanced with impurities rich in holes which are the positive charge carriers), and a pnp transistor has two semiconductor junctions that share a thin middle negatively enhanced region (material is enhanced with impurities rich in electrons, the negative charge carriers).

C. It is made from three layers of semiconductors
