Answer:
D) To gain access to low-cost inputs of production
Step-by-step explanation:
Since Gazprom is the world's largest natural gas producer, its operation costs must be relatively low due to economies of scale. Since Exxon Mobile is setting a new plant in Azerbaijan, it will need a large supply of natural gas and the cheaper it is, the better. In this case, Gaxprom provides the raw material and Exxon Mobile processes the materials.
