I have a question about environmental science…….

1. A good example of source reduction would be:
A: Burning old tires to create usable energy.
B: Finding uses for discarded computers.
C: The lighter weight of aluminum cans as opposed to years ago.
D: Installing air pollution control devices in incinerators.
E: Increasing the percentage of paper, glass, and aluminum that is
recycled in the U.S.

In my book it says the source reduction is a strategy where industries can often design and manufacture their products in ways that decrease the volume of solid waste and the amount of hazardous materials in the solid waste stream.
It also says that it is the most underutilized aspect of waste management and that it is accomplished in a variety of ways, such as substituting raw materials that introduce less waste during the manufacturing process and recycling and reusing wastes at the plants where they are generated.

I just don’t comprehend the question. I don’t think the answer is B or D but correct me if I’m wrong. Can you please give me a detailed explanation of the answer as well.

Thank You So Much
B doesn’t make since. Because the definition of source reduction states that it is all about reducing waste at the source of the product when it is made. Not after it has already been made.
