Explanation:
When a material undergoes work hardening, the dislocations in the material increase and become entangled. This makes it harder for them to move and causes the material to become stronger and more brittle. As a result, the ductility of the material decreases.
The ductility of a material is the ability to deform under tensile stress by stretching or elongating without breaking. If a material has low ductility, it will fracture easily when subjected to stress.
Therefore, when a material undergoes work hardening, its ductility decreases because the material becomes more brittle and prone to fracture. This is why the correct answer to the given question is option 'B'.
