Detailed Solution

The above statement is true.
Since aluminium is a good conductor of electricity and can conduct the electric current through it, hence the bulb will glow.
Conductors are substances that allow electricity to pass through them, as metals are good conductors of electricity. Aluminium is also metal, so it can glow the bulb due to its conductivity property. Other conductors of electricity are copper, steel, iron, and mercury.
