Practice question
Question
What distinguishes a ductile material from a brittle material in terms of stress-strain behavior?
Explanation
A ductile material undergoes significant plastic deformation before fracture, allowing it to withstand larger strains, while a brittle material fractures with minimal plastic deformation. As per NCERT, applying relevant law/formula with correct units and sign convention leads to Ductile materials undergo significant plastic deformation before fracture. This satisfies dimensional consistency and physical conditions given, so option B is scientifically correct.
