What uncertainty affects the sustainability of ABC's competitive advantage in a circular model?

• A. It is irrelevant whether competitors imitate it.
• B. The sustainability of ABC's competitive advantage is hard to evaluate without knowing how easily competitors could imitate its resource recovery model.
• C. It will be sustainable regardless of imitation.
• D. It is guaranteed that competitors cannot imitate its model.

Answer: (B)

In a circular business model, the length of a competitive advantage depends on how easily others can copy the resource recovery system. The uncertainty that matters here is imitability: if rivals can replicate ABC’s processes, network, and partnerships for recovering materials and turning them into value, the advantage won’t last long. If imitation is difficult—due to unique data, tech, supplier networks, or trusted relationships—the advantage can be more durable.

So the best choice is the one that says sustainability is hard to evaluate without knowing how easily competitors could imitate its resource recovery model. This captures the idea that the main risk to ABC’s edge comes from the potential for others to replicate the circular processes, eroding the advantage over time.

Other options ignore or misstate this dynamic. If imitation is irrelevant, you’re discounting a core driver of durability. Claiming it will be sustainable regardless of imitation or that competitors cannot imitate at all ignores the reality that many circular innovations can be copied with enough effort, reducing long-term advantage.
