Best answer
The correct option is (a) Petrol engines

Explanation: At low boiling fractions of petroleum least amount of impurities are left and since the efficiency petrol engine decreases with the increase in the amount of impurities, these fractions are used in petrol engines. At high boiling fractions, diesel engines and oil fired furnaces are used.
