Question

which nonrenewable resource cannot be recycled?
copper
iron
aluminum
oil

Explanation:

Copper, iron, and aluminum are metals (mineral resources) that can be recycled. Oil is a fossil fuel (a nonrenewable resource) and once burned, it cannot be recycled in the same way as metals. When oil is used as fuel, it undergoes combustion and is converted into energy, carbon dioxide, water vapor, etc., and the original oil resource is consumed and cannot be reclaimed or recycled to its original form for reuse as oil.

Answer:

D. oil (assuming the options are labeled A to D as A. copper, B. iron, C. aluminum, D. oil)
