Quizplus · Accepted Answer

Cooking gas (also known as liquefied petroleum gas or LPG) is the least viscous among the given options. It is a gas at room temperature and therefore does not exhibit significant resistance to flow. Gasoline and motor oil are both liquids and have higher viscosities than cooking gas. Tar, on the other hand, is a highly viscous and thick liquid and hence has the highest viscosity among the given options.
