Which of the following statements best explains why equilibrium cooling of a liquid alloy of eutectic composition beyond the eutectic temperature yields a microstructure consisting of alternating layers of two solid phases. O The solidification process is dependent upon physical rearrangement of atoms across small length scales. O Solidification of an alloy with eutectic composition is diffusion-dependent and occurs at a single temperature. O The two solid phases produced from solidification of an alloy with eutectic composition have drastically different chemical compositions. O Since the process is diffusion-dependent and occurs across a narrow temperature range, alternating layers are produced because the diffusion path length is minimal.
