In the 1970's these two countries represented roughly 48% of OPEC's total production.

• A. Iran and Iraq
• B. Saudi Arabia and Kuwait
• C. Venezuela and Saudi Arabia
• D. Iran and Saudi Arabia

Answer: (D)

In the 1970s, OPEC’s output was driven mainly by two producers: Saudi Arabia, the largest single supplier, and Iran, the second-largest until the 1979 revolution. Their combined output accounted for roughly half of OPEC’s total production, about 48%, which is why this pairing is the best match. This reflects how OPEC’s influence rested on the capacity of its biggest members, with these two contributing the majority share while other members produced smaller amounts.
