Explanation:
Conduction is the transfer of heat from one object to another by direct contact. In order for conduction to occur, the following conditions must be met:
Bodies should be in contact
Conduction requires that the two bodies be in contact with each other. Heat is transferred from the hotter body to the colder body through direct contact between the two. If the bodies are not in contact, conduction cannot take place.
Bodies should have different temperatures
Conduction takes place only when there is a temperature difference between the two bodies. Heat flows from the hotter body to the colder body until both reach the same temperature. If the bodies have the same temperature, there will be no heat flow and hence no conduction.
Conduction is possible even if the bodies are apart from each other
Conduction occurs only when the two bodies are in direct contact, but this contact need not be physical. Heat can be transferred through a medium such as a metal rod or a wire. In this case, the two bodies need not be in physical contact but can be separated by a distance.
Conclusion:
Based on the above discussion, we can conclude that option D is the correct answer. Conduction requires that the two bodies be in contact and have different temperatures. If the bodies are not in contact, conduction cannot take place. If the bodies have the same temperature, there will be no heat flow and hence no conduction.

Bodies Should be in contact with each other for the heat to transfer and should be both in different temperatures because they both would stop and become the same temperature at one point so that's the exact answer.
