Show Hint
- A, B and C only
- B, C and D only
- A, C and D only
- A, B and D only
The Correct Option is B
Solution and Explanation
Step 1: Evaluate each statement.
- (A) Incorrect: Malleability is the ability to withstand plastic deformation under compression (hammering into sheets), not limited to elastic energy.
- (B) Correct: Toughness is the capacity to absorb energy up to fracture (entire stress-strain area).
- (C) Correct: Resilience is the elastic energy stored, i.e., the area under the stress-strain curve up to the elastic limit.
- (D) Correct: Brittle materials fracture almost immediately after the elastic limit, showing negligible/no plastic zone.
Step 2: Conclusion.
Correct set of statements = (B, C, D).
