All of the following are good conductors of heat exept a. Wood
b. Aluminum
c. Copper Silver

(Sorry if its the wrong subject, Im not sure which science this is.)

A, wood

Explanation; Wood is a poor conductor of heat (as well as other forms of energy) because it is covalently bound as a compound. As a result, it does not have the free electrons that scatter about to conduct different forms of energy like metals and other strong conductors do.
