So we know that a conductor is a poor insulator since it will absorb the heat and relay it to the environment.  The only good conductor above is Aluminium Foil since it is made of the metal aluminum (metals has a sea of electrons that are able to transfer heat).  As a result the answer is Option 4.

All the others will insulate since they are not able to transfer the heat because of the absence of free electrons.

Aluminum foil is NOT an example of an insulator.

What is an insulator?

  • A substance that does not allow the passage of heat or charge.

According to the options:-

a.  wood-insulator

b.  plastic-insulator

c.  glass-insulator
