Suppose there is a decrease in the price of butter.There will be an increase in demand for bread.
Option (B) is correct
Step-by-step explanation:
Bread and butter are complementary goods. They are demanded and consumed together. So their demand are positively correlated which means an increase in demand of one will lead to the same increase the demand of other
If the Price of butter decreases, it will lead to an increase in the demand for butter. With the increasing demand for butter, the demand for bread will automatically increase. Both demands will move in the same direction.
