Answer: Option (D) is the correct answer.
Explanation:
When we use an object or substance in excess then it is likely that the substance will run out with time. But at the same time, if we use that substance according to its requirement and try to conserve it as much as we can then we can preserve the substance.
Hence, it is good to avoid wastage of a substance and balance its use according to the need.
Therefore, we can conclude that in the given situation yes, there is a problem with the solution as the need to conserve copper must be balanced with use.
