Answer:
a. Scientific discovery leads to an invention, the engineering team designs the product, it is then manufactured, and finally the marketing team promotes it.
Step-by-step explanation:
In the science-push we start from a scientific invention. The research and development generates the product (engineering team in this case) and then it moves into the production line and commercialization
This is the opposite to demand-pull model under which the marketing team discovers a need, R&D comes up with the product concept that is refined by the engineering team, the manufacturing team then produces it, and finally the product is sold.
