Explanation:

To determine the correct answer, we analyze Rockefeller's business practices in building his oil monopoly:

• The first option about controlling all production aspects is not the main practice for his monopoly.
• The second option about adding new products with refinery purchases is not the key practice.
• The third option: Rockefeller made profits and reinvested them to expand or buy other businesses. This aligns with his strategy of vertical and horizontal integration to build the monopoly.
• The fourth option about selling businesses for profit to buy others is not his main approach; he focused on acquiring and expanding, not selling.

Answer:

C. In all his businesses, Rockefeller made a profit and used it to expand or buy other businesses.
