Correct answer is: Wood

Explantaion:

The first wheels were made of wood. Early wheels were simple wooden disks with a hole for the axle. Some of the earliest wheels were made from horizontal slices of tree trunks. However, a wheel made from a horizontal slice of a tree trunk tends to be inferior to one made from rounded pieces of longitudinal boards 1.

The invention of the wheel is believed to have occurred around 3500 BCE in Mesopotamia (modern-day Iraq). The earliest depiction of a wheeled vehicle is found on a piece of pottery called the Bronocice pot, discovered in Poland and dating back to at least 3370 BCE 2. The wheel was initially used for pottery, but it eventually found its way into transportation, particularly on chariots.

It is important to note that the exact origins of the wheel are uncertain, as it was invented before written records were kept. Therefore, it is difficult to determine who exactly invented the wheel or which tribe had the idea 3 4.
