The family is planning to replace their air conditioner. The wife says: "This year we need to save money, so we shouldn't buy such an expensive air conditioner." The husband says: "This air conditioner is expensive, but it's first-class energy efficient, saves electricity in the long run, and our current one has been used for eight years with rising maintenance costs." Analyzing with the law of contradiction, what is the relationship between their statements?

Answer: B

• ATrue contradiction: the wife says to save money, the husband wants to spend, the two judgments cannot both be true under the same condition.✗ Incorrect. The two are talking about different scopes of "saving": the wife emphasizes the current budget, the husband considers long-term operating costs and old unit maintenance expenses; they are not contradictory under the same standard.
• BApparent contradiction: the wife cares about this year's cash flow, the husband cares about the total cost over the next few years; the conditions differ, so both can be true.✓ Correct. This is an apparent contradiction caused by different time frames and expenditure scopes; the key is to clarify the meaning of "saving money" and the time range being compared.
• CViolates the law of identity: the husband has equivocated on the concept of "saving", so his words are not worth discussing.✗ Incorrect. The husband is supplementing the dimension of "saving more in the long run", not switching meanings within the same concept; directly accusing the other of equivocation is concluding without checking the conditions.
• DThere is no contradiction, because saving and spending are two completely different things, and no conditions need to be confirmed.✗ Incorrect. Although it's not a true contradiction, to confirm what "saving" refers to (budget scope, time frame, whether long-term electricity costs are included) is necessary; one cannot simply say there is no relationship.
