C Correct answer
Explanation

A spoon in a cup of boiled milk will be hot as heat transfers from the milk at a higher temperature to the spoon at a lower temperature. Glowing light bulb will also be hot as electric current causes heating effect. Wood is an insulator, i.e. it does not conduct heat. Iced tea and ice cream will also be cold.
