Smart consumer behavior, as advocated in the text, involves looking up item prices from different stores before making a purchase, emphasizing informed decision-making and potential cost savings.
The correct answer is option C.
Smart consumer behavior is exemplified by option C: looking up how much an item costs from different stores. This reflects a proactive approach where consumers gather information before making a purchase, considering the costs and benefits associated with the item. The provided text emphasizes the importance of consumers weighing the significance of an item in their lives, considering health, happiness, and potential opportunities for increased income.
Contrastingly, options A and D suggest impulsive buying and purchasing items known not to be needed, which are examples of less prudent consumer behavior. Impulse buying may lead to regrets and financial strain, while purchasing unnecessary items contradicts the principles of smart consumption outlined in the text.
Option B, buying an item without researching it first, also goes against the advocated approach of making informed decisions. The text encourages consumers to use resources like the internet to gather information, compare prices, and make well-informed choices to save money.
In summary, the example of smart consumer behavior aligns with option C, as it involves researching and comparing prices before making a purchase, contributing to wise decision-making and potential cost savings.
