What happens to the quantity demanded of a good when its price decreases according to the Law of Demand?

The correct choice reflects the fundamental principle of the Law of Demand, which states that all else being equal, when the price of a good decreases, the quantity demanded for that good typically increases. This relationship occurs because consumers find the product more attractive at lower prices, often leading to increased purchases.

When the price drops, the good becomes more affordable, encouraging existing consumers to buy more of it and potentially attracting new consumers who may not have purchased it at the higher price. This increase in quantity demanded illustrates the inverse relationship between price and quantity demanded highlighted by the Law of Demand.

In summary, a decrease in price leads to an increase in quantity demanded due to the enhanced attractiveness of the good, which aligns perfectly with the principles of consumer behavior in economics.
