Cold working of metal increases

A Tensile strength
B Yield strength
C Hardness
D All of these

Correct Answer: All of these

An example of desirable work hardening is that which occurs in metalworking processes that intentionally induce plastic deformation to exact a shape change. These processes are known as cold working or cold forming processes.
The cold working of the metal increases the hardness, yield strength and tensile strength.
