The correct answer is (a) Iraq.
Kirkuk, Mosul, and Basra are all major petroleum producing cities in Iraq. Kirkuk is located in the northern part of the country, Mosul is located in the central part of the country, and Basra is located in the southern part of the country.
Iraq is one of the world’s largest oil producers. In 2019, Iraq produced an average of 4.6 million barrels of oil per day. Iraq’s oil reserves are estimated to be 145 billion barrels, which makes it the fifth largest oil reserve in the world.
The oil industry is a major contributor to Iraq’s economy. In 2019, the oil sector accounted for 60% of Iraq’s government revenue and 90% of its export earnings.
The oil industry in Iraq has been plagued by violence and instability since the 2003 invasion of Iraq. The Islamic State of Iraq and Syria (ISIS) seized control of Kirkuk and Mosul in 2014. ISIS was eventually defeated in 2017, but the oil industry in Iraq has still not fully recovered.
Despite the challenges, the oil industry in Iraq is expected to continue to play a major role in the country’s economy. The Iraqi government is working to attract foreign investment to the oil sector and to increase oil production.
