Answer:
Hardness, Strength and Ductility can be affected by heat treatment.
The correct option is option (d).
Step-by-step explanation:
Heat treatment involves heating the material.
Heating leads to a change in the microstructure and stability of the molecules.
Hence, it also leads to changes in material properties.
Hardness is the ability of any material to resist a localized deformation.
Strength is defined as the ability of the material to withstand the load.
Ductility is the ability of the material to be drawn into a wire.
Hence the correct option is (d), which is all of the following.
