The most commonly used fuel for running automobile engines is?

Diesel
Gasoline
LPG
Propane

The correct answer is: Diesel

Gasoline is the most commonly used fuel for running automobile engines. Diesel engines are used in heavy-duty vehicles such as trucks and construction equipment, but they are not as common in regular automobiles. LPG (liquefied petroleum gas) is a mixture of propane and butane and is typically used for heating or cooking purposes, rather than powering engines. Propane is often used as a fuel for forklifts or outdoor grills, but is not commonly used in automobile engines. Therefore, the most commonly used fuel for running automobile engines is gasoline, making option B the correct answer.
