Answer:
The correct answer is option D.
Explanation:
An increase in the price of the commodity causes its quantity demanded to decrease. This is because of the law of demand. There is an inverse relationship between the price of a commodity and its demand.
So a decrease in quantity demanded means that the price has increased. It is indicated by an upward movement on the same demand curve.
A decrease in price, on the other hand, will lead to an increase in the quantity demanded. This will cause a downward movement on the same demand curve.
The movement along the demand curve occurs when there is a change in price, but not the other factors.
There is upward movement along the demand curve when quantity demand decreases in response to a change in price.
The movement along the demand curve occurs when there is a change in the price and other factors remain constant.
This would result in rightward or leftward movement along the same demand curve, it gives the rightward movement when the price of any goods goes up and vice versa.
Therefore, The quantity demanded decreases in response to changes in price, which leads to an upward movement along the demand curve.
Hence, option D is correct.
