Which of the following materials is used to make a semiconductor?
- ACopper
- BSulphur
- CSilicon
- DTantalum
Correct answer: C — Silicon. From the official ISED question bank, verified word for word.
Why
Silicon is the correct choice because it is a semiconductor, a material that conducts electricity better than an insulator but not as well as a metal, making it ideal for building transistors and diodes. The full explanation — and one for every question — is in Pro.
