Answer:
A) product champions.
Step-by-step explanation:
In marketing, a product champion is the first person that is able to see the potential success of a new product or service and tries to convince potential investors or department heads. The product champion is the individual that promotes the products or service within the organization. Sometimes great products are lost because they do not have a product champion.
E.g. Microsoft's tablet was launched many years before the iPad, and if you compare it to existing technology in 2000 it was revolutionary. But its launch was very timid and soon Microsoft abandoned the project. Later Steve Jobs introduced the iPad and it was an immediate success. Microsoft's tablet obviously didn't have a product champion that pushed for its massive release, while Steve Jobs was the iPad's champion.
