Brittle failure is a type of failure in which: (a) There is large amount of plastic deformation (b) Large amount of elastic deformation (c) Very little plastic and elastic deformation (d) None of the above

c). Very little plastic and elastic deformation

Explanation:

Brittle failure is a sudden, very rapid crack where there is no sign of any plastic deformation or ductility. The failure is not stable unlike ductile failure and the the crack propagates very fast without any further increase of any stress. In brittle failure there is very little plastic deformation and low energy is absorbed before fracture takes place.

Thus, very little plastic and elastic deformation takes place in brittle failure.
