Best answer
Correct answer is (a) brittleness

To explain I would say: The tendency of a material to fracture without changing it’s shape is known as brittleness. Hardness of a material is its tendency to resist penetration. Elasticity of a material is the property of the material to return to its original shape once the force causing the distortion of shape is removed.
