Answer:
The correct answer is option c.
Step-by-step explanation:
An increase in the price of oil will cause the quantity demanded of a commodity to decline and the quantity supplied to increase. This will cause a surplus in the market.
There will be no change in the demand and supply curve.
This is because of the law of demand and supply.
According to the law of demand, the price of a commodity is inversely related to the quantity demanded of the commodity, while other factors are kept constant.
Similarly, the law of supply states that the price of a commodity is positively related to the quantity demanded of a commodity.
The demand and supply curves are not affected by the changes in price, they change as a result of changes in other factors.
