Hint: In order to answer the question, to know which option is correct, we will explain the reason why heat conduction is the property of one of the options, and then we will also explain about the correct option.

Complete answer:
Heat conduction is the property of metals. The valence electron in metals is free to move between the atoms. As a result, metals are excellent electrical conductors. These electrons can also transport energy in the form of heat, making metals heat conductors.
Heat is a fascinating form of energy. It not only sustains life, provides warmth, and aids in the preparation of food, but it also plays an important role in many fields of scientific study. Anything from building heaters to understanding seasonal change to sending ships into space is governed by understanding how heat is transmitted and the degree to which different materials can exchange thermal energy.
There are only three ways to transfer heat: conduction, convection, and radiation. Conduction is the most common of these, and it happens frequently in nature. In a nutshell, it's the process of transferring heat by physical touch.

Hence, the correct option is (B).

The rate of conduction heat transfer is proportional to the thermal conductivity of the material. For example, if all other parameters are equal, the rate of conductive heat transfer in copper will be higher than in plastic.
