Answer:
Option (b) is correct.
Step-by-step explanation:
Raclette is a popular wintertime dish in Switzerland. Both Raclette cheese and boiled new potatoes are used together to make Raclette.
Therefore, Raclette cheese and boiled new potatoes are complimentary goods because both are used together to satisfy a given want.
In case of complimentary goods, there is an inverse relationship between the price of a good and demand for its complimentary good.
Hence, if there is a decrease in the price of Raclette cheese then as a result the demand for new potatoes increases.
So, the correct option is (b).
