The correct answer is: C. upwards to the left
A demand curve is a graph that shows the relationship between the price of a good and the quantity demanded of that good. The normal demand curve slopes downwards to the right, which means that consumers demand more of a good when the price of that good decreases. However, there are some cases where the demand curve can slope upwards to the left. This is known as an exceptional demand curve.
An exceptional demand curve can occur when there is a strong psychological attachment to a good. For example, some people may be willing to pay more for a particular brand of clothing or car, even if there are other brands that are available at a lower price. In this case, the demand for the good is not driven by its price, but by the consumer’s emotional attachment to the brand.
Another example of an exceptional demand curve is when there is a limited supply of a good. For example, if there is a new movie that is only available in a limited number of theaters, people may be willing to pay more to see the movie, even if it is available at a lower price later on. In this case, the demand for the good is driven by the fact that it is scarce.
Exceptional demand curves are relatively rare, but they can have a significant impact on the market for a good. When the demand curve slopes upwards to the left, it means that the quantity demanded of a good increases as the price of that good increases. This can lead to higher prices for the good, and it can also lead to shortages of the good.
In conclusion, an exceptional demand curve is one that slopes upwards to the left. This can occur when there is a strong psychological attachment to a good, or when there is a limited supply of a good. Exceptional demand curves are relatively rare, but they can have a significant impact on the market for a good.
