Life cycle analysis in product design considers:

Life cycle analysis in product design plays a crucial role in assessing the overall environmental impact of a product throughout its entire life span, from conception to disposal. This comprehensive approach evaluates various stages, including raw material extraction, manufacturing, transportation, usage, and end-of-life processes such as recycling or disposal. By considering all these phases, designers can identify opportunities to minimize negative environmental effects and enhance sustainability.

The other choices focus on narrower aspects that do not capture the holistic perspective of life cycle analysis. For example, limiting the analysis to the manufacturing phase neglects other critical stages that contribute to a product's total environmental footprint. Similarly, considering marketing costs or sales strategies does not align with the environmental and sustainability focus of life cycle analysis, which prioritizes the ecological impact rather than economic factors. Thus, the correct choice reflects the comprehensive nature of life cycle analysis in product design.
