Correct option is D
The correct answer is (d) Diesel.
· Diesel is the primary product of petroleum used to power heavy vehicles such as trucks, buses, and construction equipment.
· Diesel engines are favored for heavy vehicles because they are more fuel-efficient than petrol engines and provide higher torque, which is necessary for carrying heavy loads.
· Diesel fuel is derived from the fractional distillation of crude oil and is denser and more energy-efficient than petrol, making it ideal for long-haul transportation and heavy-duty applications.
Additional Knowledge:
· Kerosene: Kerosene is used for heating and jet fuel, but it is not typically used to power heavy vehicles.
· Petroleum gas: This refers to liquefied petroleum gas (LPG), which is used in cooking and heating but not for heavy vehicles.
· Petrol: Petrol is used primarily for smaller vehicles like cars and motorcycles but is not typically used for heavy-duty vehicles.
