Final answer:
The correct changes in supply and demand that will lead a product to become less scarce are decreased demand and increased supply.
Step-by-step explanation:
In this question, we are looking for the changes in supply and demand that will lead to a product becoming less scarce. The correct answer is option A: decreased demand, increased supply.
When demand for a product decreases, there is less competition among buyers, which can lead to lower prices. On the other hand, when supply of a product increases, there is more availability, which can also lead to lower prices. Therefore, when both demand and supply decrease, the product becomes less scarce.
Example:
Let's say there is a high demand for a specific smartphone. The supply is limited, making the product scarce. However, if the demand decreases (maybe due to the release of a newer model), and at the same time, the supply increases (maybe due to the manufacturer producing more units), the product becomes less scarce.
