Answer:
A) when designing and launching a new product or service.
Step-by-step explanation:
Diversity is important when designing and developing a new product or service because diverse people will tend to have different opinions and ideas. The more ideas you can come up with at the first stages, the better.
As the development process continues, the team usually requires the participation of people from different units, e.g. product design, marketing, finance, manufacturing, etc., and everyone is responsible for checking how plausible the new product is.
E.g. imagine that the product design unit developed a great phone, uses 3D holograms, works better than any other phone the competition might offer, its battery lasts for a whole month, whatever you might imagine, want or need, but it costs $50,000 to produce. At that point you realize that someone from the financial department would have stopped that non-sense before wasting so much time.
