Solution
The property of metals that makes them good conductors of heat is A. Their mobile electrons.
Here's why:
Metals have a sea of free electrons that are not bound to any particular atom. These electrons are free to move throughout the metal, and they can carry thermal energy from one place to another. This is what makes metals good conductors of heat.
The other options - hardness, melting point, and ductility - are not directly related to a metal's ability to conduct heat. Hardness is a measure of how resistant a material is to deformation, melting point is the temperature at which a substance changes from a solid to a liquid, and ductility is a measure of a material's ability to deform under stress without breaking. None of these properties have a direct impact on a metal's thermal conductivity.
