    For a ductile material, toughness is a measure of ability to absorb energy up to fracture. (Toughness is the ability of a material to absorb energy and plastically deform without fracturing. )

    Simply the toughness is the property of material in which it can absorb energy upto fracture. So, option (b) is correct.
    For further explanation we can go through the stess-strain diagram of a ductile material and we will see there that the area covered under curve from elastic limit to fracture point is considered as toughness.

    Happy Learning. 🙂
