Best answer
The correct choice is (d) Aluminum

For explanation I would say: Recycling is reusing some components of the waste that has some economic value. Aluminum can be recycled many times.  Mining of new aluminum is expensive hence recycling of aluminum plays a significant role in aluminum industry.
