| 金声玉亮2.0 | C. A negative cross-price elasticity Explanation: Complementary goods are products that are used together, such as peanut butter and jelly. When the price of one good increases, the demand for the other good decreases. This is reflected in a negative cross-price elasticity, which measures the responsiveness of the demand for one good to changes in the price of another good. A negative cross-price elasticity indicates that the two goods are complements. The other options are incorrect because: A. A positive income elasticity indicates that a good is a normal good, not a complement. B. A horizontal demand curve indicates that the demand for a good is perfectly elastic, but it does not provide information about the relationship between two goods. D. A demand elasticity greater than one indicates that the demand for a good is elastic, but it does not provide information about the relationship between two goods. |

| deepseekr1 | Answer: C Complements are goods used together, leading demand for one to decrease when the price of the other rises. Cross-price elasticity measures this relationship: a negative value indicates that as the price of one good increases, demand for the complement decreases. Other options relate to income elasticity (A), demand curve shape (B), or own-price elasticity (D), which do not directly address complementarity. |

| kimi | C. A negative cross-price elasticity Complementary goods are those whose demand for one increases as the price of the other good increases. A negative cross-price elasticity indicates that the two goods are substitutes, meaning that if the price of one good increases, consumers will buy more of the other good. However, the question asks for the indication of complements, and the correct answer should be the opposite of substitutes, which is not listed in the options provided. If we assume that the question is asking for the characteristic of substitutes, then the correct answer would be C. But since complements are typically indicated by a positive cross-price elasticity (where the demand for one good increases as the price of its complement decreases), none of the options provided directly indicate that two goods are complements. |
