Final answer:
The price of a product would fall the most when the demand falls while the supply rises.
Step-by-step explanation:
To determine which situation would cause the price of a product to fall the most, we need to consider the impact of changes in demand and supply. The correct answer is B. When the demand falls while the supply rises, it puts downward pressure on the price of the product. This is because there is less demand for the product, while the supply increases, resulting in a surplus of the product in the market.
For example, let's say there is a decrease in consumer income, causing the demand for a product to decrease. At the same time, the supply of the product increases due to technological advancements or more producers entering the market. With less demand and more supply, the price of the product will fall as sellers compete to sell their excess supply.
