The correct answer is C. There are two types of flow in a semiconductor: electron flow and hole flow. Electron flow is the movement of electrons through a semiconductor material. Hole flow is the movement of positively charged “holes” through a semiconductor material. Holes are created when an electron is removed from a covalent bond between two atoms. The remaining atom has a positive charge, and this positive charge can move through the material in the same way that an electron can.
Option A is incorrect because there are two types of flow in a semiconductor. Option B is incorrect because there is more than one type of flow in a semiconductor. Option D is incorrect because there are only two types of flow in a semiconductor. Option E is incorrect because there are two types of flow in a semiconductor.
