Which of the following examples best reflects the law of supply?

The law of supply states that, all else being equal, as the price of a good or service increases, the quantity supplied also increases. This relationship between price and quantity supplied is based on the incentive for producers to supply more of a good when they can receive a higher price for it. Higher prices can lead to greater potential revenue and profit margins, enticing producers to increase their output.

In this context, when the price of a product rises, businesses and suppliers are motivated to enhance their production to take advantage of the higher prices, which in turn increases the quantity supplied in the market. This principle reflects the positive relationship between price and quantity supplied as laid out in the law of supply.
