Final answer:
The statement regarding a sales spurt before product deletion is false. The decline in a product's sales is usually due to factors such as changes in consumer preferences, demographic shifts, economic changes, and competition from substitutes.
Step-by-step explanation:
The statement 'The dropping approach to product deletion generates a sales spurt just before removing the product from the market' is False. When a product is due for deletion, various factors may lead to its decline in popularity and, consequently, declining sales. These factors can include a taste shift to lesser popularity, a decrease in the population likely to buy the product, a drop in income for consumers indicating the product is a normal good, and the fall in price of substitutes, which encourages consumers to purchase those instead.
