Solution
The correct option is D Aluminium
Cooking utensils are made up of hard materials that have high thermal conductivity, high melting, and boiling points. Chocolate wrappers are made up of very thin sheets. So, the element should be highly malleable as well. To make electric wires, the element should be ductile and conduct electricity. All these properties are satisfied only by metals.
Among the given options, carbon is a non-metal and silicon is a metalloid. Even though mercury is a metal, it exists in the liquid state at room temperature. So, aluminum is the most suitable element that can be used for all the required applications.
