Answer:
d. is negative so they are complements
Explanation:
The gasoline and driving are complement to each other that means if the price of the gasoline is increased so there should be the less pricing as it will become costlier now and if the price of the gasoline is decreased so there is more driving. It has an inverse relationship between two goods
So, the cross price elasticity of goods would be negative
Hence, the option d is correct
