The topic is frequently linked with current affairs on oil supply cuts, inflation, and India’s energy security.Explanation— OPEC+ is set to agree on a modest oil output hike, according to sources who spoke to news agency Reuters.

The move comes as a way to show the group is ready to raise global supplies once the war stops.— Brazil and the United States are not members of OPEC+.Therefore, option (d) is the correct answer.Story continues below this adQUESTION 2With reference to the African Lion exercise, consider the following statements:1.
