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!

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