Andrew noticed that the plastic in his chair seat didn't feel as cold as the metal legs. What statement best explains this observation?

A) Plastic is an insulator, so it stores warmth in the room.
B) The metal absorbs cold air in the room at a faster rate than plastic.
C) Metal is a conductor of heat so it transmits warmth away from Andrew's hand at a faster rate than plastic.
D) Metal is a conductor of heat, so it transmits its heat to the plastic until the plastic reaches room temperature.
