LCA is a systematic method that traces all relevant environmental inputs and outputs associated with a product throughout its life. It considers energy and material use, emissions and waste in each stage, from resource extraction to manufacturing, distribution, use and end-of-life management. By revealing "hotspots" of impact, LCA helps designers, firms and policymakers compare alternatives and choose options with lower overall environmental burdens.

Option A:
Option A is incorrect because LCA goes far beyond economic costs; it focuses on environmental impacts, although economic information can be analysed alongside it.

Option B:
Option B is correct since it captures the cradle-to-grave scope and environmental focus that define LCA.

Option C:
Option C is incorrect as market share analysis belongs to marketing and business studies, not to environmental life-cycle assessment.

Option D:
Option D is incorrect because assessing social reputation involves perception surveys and branding studies; it is not the primary goal of LCA tools.
