● When we take into consideration the thermal conductivity of the objects mentioned in the question the correct choice is option B.
● Thermal conductivity is the ability to conduct heat and when compared to steel water and wood Steel has more then the other two mentioned objects or items.
● This is because steal immediately conducts heat as it has closely packed atoms and water is medium conductor as it has to absorb heat first and then conduct would cannot conduct heat because it itself gets burnt.
