Answer:
France
Explanation:

The correct answer is D) hot dogs and hot dog buns.
If hot dogs go on sale, the number of hot dogs demanded will increase. At the same time, demand for hot dog buns, regardless of if buns are on sale or not, will also increase because they are a complementary product.
If the price of hot dog buns were to increase drastically, the consumption of both products would likely decline.
