Semi-conductors are materials that a) are good conductors. b)allow electron flow and resist neutron flow. c)have insulator and conductor properties. d)allow neutron flow. semi-conductors are materials that have insulator and conductor properties.

c)have insulator and conductor properties.

Explanation:

Semiconductors, as the name suggest have properties of both insulators and conductors. Until the current/voltage applied to them reaches a particular threshold they work like an insulator. Once the threshold is crossed they behave like a conductor. This property makes them very useful in electronic devices. In fact almost all the electronic equipment in today's age use semiconductors in some way or the other.
