Final answer:
Expensive products that consumers purchase less frequently in the consumer product categories are known as shopping products (option D). These often include durable goods like cars and refrigerators which are part of the same economic share as nondurable goods.
Step-by-step explanation:
In the context of consumer product categories, expensive products that consumers buy less frequently are known as d. shopping products. These items include long-lasting durable goods such as cars and refrigerators, that have more value and require more thoughtful consideration before purchase when compared to everyday consumable items like food and clothing. Shopping products are found in the same economic share as nondurable goods, even though they are purchased less often. Such goods often involve a higher outlay of money, less frequent purchasing, and they play a significant role in the economic structure alongside inventories, structures, and non-durables in the marketplace.
