[amp_mcq option1=”germanium” option2=”silicon” option3=”carbon” option4=”none of the above” correct=”option2″]
The correct answer is B. silicon.
Germanium was the first semiconductor used in transistors, but it was soon replaced by silicon because it is more stable and has a higher resistance to heat. Silicon is also more abundant than germanium, which makes it cheaper to produce.
Carbon is not a semiconductor. It is a conductor of electricity.
The other options are incorrect.
