Concept:OPEC coordinates oil policies among member countries to stabilise the global oil market.
Explanation:• OPEC stands for the Organization of the Petroleum Exporting Countries.
• It represents major oil-producing nations that work together on petroleum policies.
• One key objective is to stabilise oil prices in the world market.
• Another objective is to secure steady income for oil-producing countries.
• OPEC also ensures that oil flows reliably to consuming countries.
• However, setting up petroleum refineries in every member country is not one of OPEC's stated objectives.
• Refinery development is left to the individual decisions of each member state, not OPEC as a group.
• Therefore, the option that does not list an OPEC objective is the one about establishing refineries in all member states.
Answer:B. to establish petroleum refineries in all member states.
