Answer:
Option (d) is correct.
Explanation:
While drawing a demand curve, a price of the good is represented on the vertical axis and the quantity demanded for the good is represented on the horizontal axis.
There is an inverse relationship between the price and the quantity demanded for the goods. That's why the demand curve is downward sloping. This means that as the price of the good increases then as a result the quantity demanded for that good decreases and as the price goods decreases then as a result the quantity demanded for those goods increases.
