Answer:
The answer is less of good B being sold
Step-by-step explanation:
Complementary goods are goods that are consumed together, for example, bread and butter, cars and fuel. These goods are consumed in pairs together.
Increase in price of good A will lead to decrease in demand of good A(the law of demand -.the higher the price, the lower the quantity demanded and vice-versa), because they are are both complementary goods, the demand for B will also be reduced. Like now, if the price of car increases, people will reduce buying cars and this has an effect on consumption of fuel too because the number of people buying fuels will also reduce
