Answer : The correct option is, (C)X: paper Y: silicon
Explanation :
Conductor : Conductors are those substance which have ability to pass electric current through them. Most of the metals are good conductors.
For example : copper, gold, silver, aluminium, etc.
Insulator : Insulators are those substance which do not have ability to pass electric current through them.
For example : wood, plastic, glass, paper, etc.
Semiconductor : Semiconductors are those substance which have ability to allow or suppress the electric current.
For example : carbon, silicon, germanium, etc.
Superconductor : Superconductor are those substance which conduct electricity with zero resistance.
For example : mercury, lead, etc.
Thus, 'X' will be paper and 'Y' will be silicon.
