안녕하세요 선생님

문제 관련해서 문의 드립니다.

13. Regarding sustainability, a company will evolve through three stages as they adopt
sustainability strategies. What is a tool, used in stage 2, to help a company produce cost
advantages associated with sustainability?

A. Activity based costing.
B. Life cycle costing
C. Product life cycle management
D. Life cycle analysis

해당 답은 B로 알고있씁니다 D가 안되는 이유는 Life cycle analysis는 environmental and social impacts에 대한 분석으로 알고 있습니다.

하지만 아래 91번은 답이 C인이유가 잘이해가 안되서요 A에 더 답이 가깝지 않을까 생각이 드는데 검토 부탁 드리겠습니다.
