During an investigation, Rachel placed two spoons in a pan of water on a heated hot plate. One spoon was made of wood and the other was made of metal. After several minutes, the metal spoon became much hotter than the wooden spoon. This most likely happened because:

Both are good thermal conductors.
The wooden spoon was larger, therefore harder to heat.
Wood reflects thermal conduction.
