The first answer is correct (A).
In economic theory, through the interaction between supply and demand one obtains the price and equilibrium quantity of a good.
The demand for a good is directly associated with consumer preference. If a released product succeeds, its demand is initially high, like the red line on the chart.
However, over time, consumers' preference for the good may decrease (like the blue line) for a number of reasons, such as the launch of a substitute good, the herd effect or a decrease in euphoria by the product, making it less popular, such as item (A) of the question.
