Answer is Right!
Answer is Wrong!
The correct answer is: B. In the opposite direction.
Complements are goods that are used together, and if the price of one complement changes, the demand for the other complement will change in the opposite direction. For example, if the price of coffee goes up, the demand for coffee creamer will go down, because people will be less likely to buy coffee if it is more expensive.
Option A is incorrect because complements move in opposite directions. Option C is incorrect because complements move in opposite directions, not in the same direction. Option D is incorrect because the answer can be determined.
