Answer:
A good conductor of heat can transmit heat by any of these processes but a bad conductor of heat doesn't allow heat to transfer from one part of a body to another. A wooden spoon is a bad conductor of heat. So, if it is dipped in a cup of ice cream, its other end does not become cold. Hence, option D is correct.

The correct option is (d) i.e. it does not become cold
- The transmission of heat energy in a good conductor is done by basically three methods convection , conduction and radiation.
- In conduction ,heat transfers from higher to lower temperature without any actual movements of the particle
- In convection , transfer of heat occurs by the movement of particles.
- While in Radiation , heat transfers in the form of electromagnetic waves and it doesn't requires any medium for the propagation of heat.
- Whereas in a bad conductor of heat there will no transmission of heat occurs and because a wooden spoon is a bad conductor of heat that's why it will not become cold and no transmission of heat will occur when dipped in a cup of ice cream.
