Answer:
Option (d) is correct.
Step-by-step explanation:
Gasoline is a normal good for the consumers. So, if there is an increase in the price of gasoline then as a quantity demanded for gasoline decreases.
Also, quantity demanded for gasoline decreases more in long run than in the short run, this is due to the elasticity of the demand curve. As we know that demand curve for gasoline is more elastic in the long run as compared to the short run.
If the demand curve is more elastic then a little change in the price of a commodity or a good tends to large change in the quantity demanded for that good.
