Which statement lists a typical stage of a life cycle assessment?

• A. Conceptual design; sourcing materials; prototyping; testing.
• B. Raw material extraction; manufacturing; distribution; use phase; end-of-life/disposal.
• C. Corporate social responsibility reporting.
• D. Market analysis and product launch.

Answer: (B)

Life cycle assessment examines environmental impacts across every stage of a product’s life from cradle to grave. The typical stages are raw material extraction, manufacturing, distribution, use phase, and end-of-life/disposal. This sequence covers resource回 extraction through production and delivery, how the product is used, and what happens when it’s discarded or recycled, which is exactly what an LCA analyzes. The other options describe development activities, CSR reporting, or marketing, which aren’t the life-cycle stages an LCA focuses on.
