According to the article, why does quantum tunneling pose a significant challenge to further miniaturization?
- A It prevents electrons from moving through the transistor when it is in the 'on' state.
- B It requires transistors to be made of expensive exotic materials to function at all.
- C It causes electrons to pass through insulating barriers, leading to energy loss and unreliability.
- D It increases the physical size of the microchip, making portable computing impossible.
