During ductile fracture, the material yields and flows plastically well before it actually separates, and this plastic flow tends to concentrate around tiny inclusions or second-phase particles scattered through the metal. As the load keeps increasing, the matrix around each of these particles pulls away and tiny cavities open up, which then grow larger as straining continues, until the thin walls of metal separating neighbouring cavities finally neck down and tear apart, joining the cavities into one continuous fracture path. Looking at this surface afterward under a microscope shows a rough, cratered texture made up of countless small cup-shaped depressions, these are the dimples left behind by the coalesced microvoids, and they are the fingerprint of a ductile failure. A brittle fracture instead shows flat, shiny cleavage facets and river-like markings from rapid crack growth along crystal planes, which is the opposite texture entirely. So the correct choice is option (B).
