For a ductile material, toughness is a measure of

1. resistance to scratching
2. ability to absorb energy up to fracture
3. ability to absorb energy till elastic limit
4. resistance to indentation

Correct Option: B

For a ductive material,toughness is a measure of ability to absorb energy up to the fracture point.

Verification:
(a) Resi stance to scrateling is resistance to abrasion.
(b) Toughness is the ability to absorb energy upto fracture.
(c) Proof resilence is the ability to absorb energy till elastic limit.
(d) Hardness the resistance to indentation.
