Answer:
c. Strategic alliance relationship
Step-by-step explanation:
An strategic alliance relationship occurs when two or more firms are working closely, in a coordinated manner, with the goal of attaining a common objective.
In other words, an strategic alliance is almost like a temporary merger between two or more companies, because attaining the common goal requires a great degree of coordination and cooperation.
In this case, a company is working closely with a supplier to develop a new technology, and one that is not easy to complete. For this reason, company and supplier must work as close as if they were one in all but name. In other words, they must form an strategic alliance relationship.
