A material that does not conduct electrical current is known as an insulator. Paper, plastic, rubber, glass, and air are all good insulators. Although a vacuum is an insulator, it is not material.

At the normal temperature (it means room temperature) semiconductor act as an Insulator or conductors, so the answer is Insulator.

Under normal conditions semiconductor also doesn't allow current through it.
It needs an external energy source.
So, the insulator and semiconductor both will be correct.

In case of insulator free electrons are very less compared to conductor since. It won't carry current.

Under Normal Condition, Semiconductors are also Behave Like Insulators. So the question is wrong I think.

But a insulator not allow the flow of current then how it can.

Insulator becomes conductive when temperature goes beyond break down level so at high voltage level current flows through it that called abnormal condition.

Insulator are materials that does not allow the passes of electricity. Why through them?

But at normal condition semiconductor work as an insulator the answer should b semiconductor I think n as temperature increases it work as conductor. So why the answer is insulator.

The answer may be semiconductor also why b/c in normal condition it doesn't allow to flow electrons. It allows electrons only when temp is critical temp & critical temp is not as a normal condition.
