The Correct Answer Is A
At absolute zero, at (0 K), the covalent bonds between atoms in a semiconductor are complete. They are held at their mean position, and cannot vibrate. As a result, there are no free electrons available for the conduction of current. Hence, the semiconductor behaves as an insulator at T=0K.
The correct answer is [A] like an insulator
