What would best explain the higher purchase price of an suv that gets low gas
mileage compared to a fuel-efficient sedan, even though the cost of
manufacturing both vehicles is the same?
a a tax exemption
b a deduction
c a tax incentive
d a tariff

Tax incentive is the correct answer. This kind of government measure is planned to cheer individuals and businesses to spend money or to save money by falling the amount of tax that they have to pay. The purchase price have taxes on it, not only the cost of manufactoring the vehicle. This is why one is lower than the other.
