Many cooking pots have hard plastic or wooden handles. What is the reason for this?

a. The handles are made from a good conductor of heat so that the heat is drawn away from the pan to protect your hands.
b. The handles are made from a poor conductor of heat so that the heat cannot be drawn into your hands as easily.
c. The handles are made from different materials to make use of the differing chemical properties to block the transfer of heat.
d. When the handles heat up, they expand more than the pot thus allowing the handles to radiate heat away more effectively.

b. The handles are made from a poor conductor of heat so that the heat cannot be drawn into your hands as easily.
