Answer:
The correct answer is option B.
Explanation:
Suppose the price of music downloads decrease, this will lead to an increase in the quantity demanded of music downloads. This will be indicated by a downward movement on the same demand curve. This is because price and quantity demanded are inversely related.
An increase in the price, on the other hand, would have led to a decline in the quantity demanded indicated by an upward movement on the same demand curve.
