Answer

Brief Explanations:

Vertical integration involves controlling different stages of the production - distribution process. Rockefeller's trust controlled oil wells (production), refineries (processing), and distribution networks, which is vertical integration. Controlling just refineries is not full - vertical integration. Purchasing coal plants or iron mines is not related to vertical integration of the oil monopoly.

Answer:

He created a trust that controlled oil wells, refineries, and distribution networks.
