Understanding the Answer

Let's break down why this is correct

Answer

When the cross price elasticity of demand between two goods is positive, it means that the two goods are substitutes for each other. This occurs because when the price of one good goes up, people tend to buy more of the other good instead, since they can replace the more expensive option with a cheaper one. For example, if the price of coffee increases, some people might buy more tea as an alternative. This shows that the demand for one good rises when the price of the other good rises, indicating they serve similar purposes for consumers. Thus, a positive cross price elasticity reflects a competitive relationship between the two goods.

Detailed Explanation

When two goods are substitutes, if the price of one goes up, people buy more of the other. Other options are incorrect because Some might think that if goods are used together, a price increase would lead to more demand; Independent goods don't affect each other's demand.
