| deepseekr1 | B. substitution effect. **Explanation:** When the price of a product decreases relative to a substitute (whose price remains constant), consumers tend to buy more of the cheaper product and less of the substitute. This change in purchasing behavior due to the relative price difference is the **substitution effect**. The income effect, in contrast, relates to changes in purchasing power from a price change, not the substitution between goods. Options C and D are not relevant to this scenario. Answer: B |

| doubao | B The substitution effect occurs when a change in the price of one good leads consumers to substitute it for another good. When the price of a product decreases while the price of its substitute remains the same, consumers are more likely to switch to or buy more of the now relatively cheaper product, which is an example of the substitution effect. |

| wenxinyiyan | B. substitution effect. Explanation: When the price of a product decreases while the price of a substitute product remains constant, and the consumer buys more of the product whose price has decreased, this is known as the substitution effect. The substitution effect occurs because, at a lower price, the product becomes relatively more attractive to consumers compared to its substitutes, leading them to purchase more of it. The income effect, on the other hand, refers to the change in consumption patterns due to a change in real income, which is not directly related to the price change of a specific product relative to its substitutes. The marginal effect typically refers to the additional impact on a variable (such as utility or consumption) resulting from a small change in another variable (such as income or price), but it is not a specific term used to describe the situation described in the question. The supply effect refers to changes in the quantity supplied of a good or service in response to a change in price or other factors affecting producers, which is not relevant to the consumer's behavior described in the question. |
