    Answer : Option B

    Explanation :

    Cold Working: Plastic deformation of metals below the recrystallization temperature is known as cold working.
    It is generally performed at room temperature.
    In some cases, slightly elevated temperatures may be used to provide increased ductility and reduced strength.
