Answer: The correct answer is a. true.
Step-by-step explanation: If there is a supply glut and demand is falling, there will definitely be a fall in price. The same principle applies if Organization of Petroleum Exporting Countries (OPEC) disagree to cut production, price for domestic crude oil would fall.
The scenario above is similar to the recent happenings regarding the impacts of coronavirus on global economy and is very fresh in our memories. According to the TheNation Newspapers, "oil prices tanked more than seven per cent at the weekend to their lowest levels since mid-2017 after Russia balked at OPEC's proposed steep production cuts to stabilize prices."
OPEC is proposing a cut in oil production, but if this is not done, the impact on Brent would be devastating as the price would fall further.
