Solution

The best thermal insulation properties would be found in a thick mug. Here's why:

A. A thick mug: The thickness of the mug provides a good amount of insulation because heat transfer is slower through thicker materials. This is especially true if the mug is made of a material with good insulating properties, such as ceramic or glass.

B. A cup made of metal: Metal is a good conductor of heat, meaning it does not have good insulating properties. A metal cup would quickly transfer heat from the liquid inside to the outside environment (or vice versa), which is not what you want in a good insulator.

C. A plastic cup: Plastic is a better insulator than metal, but it's still not as good as a thick mug. Plastic cups are often thin, which allows heat to transfer more quickly than it would through a thicker material.

D. A paper cup: Paper is a decent insulator, but it's typically very thin, which means it doesn't provide as much insulation as a thicker material would. Additionally, paper cups often can't be used with very hot liquids because the heat can cause the paper to degrade or even catch fire.

So, out of the options provided, a thick mug would have the best thermal insulation properties.
