Its other end does not become cold as wood is a bad conductor of heat.

**Explanation:**

When a wooden spoon is dipped into a cup of ice cream, only the part of the spoon that is in contact with the ice cream will become cold. The other end of the spoon, which is not in direct contact with the ice cream, will not become cold. This is because wood is a poor conductor of heat.

**Conduction:**
- Conduction is the transfer of heat through direct contact between two objects or substances.
- In the case of the wooden spoon, the heat from the ice cream is transferred to the spoon through conduction.
- However, wood is not a good conductor of heat, so the heat does not travel easily through the spoon.
- As a result, the other end of the spoon, which is not in contact with the ice cream, does not become cold through conduction.

**Convection:**
- Convection is the transfer of heat through the movement of a fluid, such as a liquid or a gas.
- In this case, the ice cream can be considered as a fluid, but convection does not play a significant role in cooling the other end of the spoon.
- This is because the spoon is not immersed in the ice cream and there is no significant movement of the ice cream around the spoon to transfer heat through convection.

**Radiation:**
- Radiation is the transfer of heat through electromagnetic waves.
- While radiation can occur between objects at different temperatures, it is not the main mechanism of heat transfer in this scenario.
- The other end of the wooden spoon does not become cold through radiation.

**Conclusion:**
The correct answer is option 'A' - the other end of the wooden spoon does not become cold. This is because wood is a poor conductor of heat, and the heat from the ice cream does not easily travel through the spoon to the other end. The spoon does not become cold through conduction, convection, or radiation.

As because it is an insulator and the heat does not transfers through molecules of the wooden spoon.
