Wood. Wood is an insulator. The other materials conduct electricity.

Depends on the circuit. There could've been aluminum foil in the circuit, but a fault in one of the wires. If this were the case none of them would light up at all. This question does not provide sufficient information to come up with a valid and logical conclusion!
People who claim wood have no proof that
1.) The light bulb is broken or two that the wires are broken.

Wood!
All the rest are metals which easily conduct electrical current which would complete the circuit and light the bulb.
