Concept:The supply curve shows the relationship between price and quantity supplied.
Explanation:A normal supply curve has a positive slope, meaning it rises from left to right.
This positive slope indicates that as price increases, the quantity supplied also increases.
Sellers are motivated by higher revenue and profit.
Therefore, they are willing to offer more goods for sale at a higher price than at a lower price.
A lower price reduces the incentive to supply, while a higher price attracts more supply.
Thus, the positive slope directly reflects sellers' greater willingness to sell at higher prices.
Answer:C. sellers are willing to sell more at a higher price.
