The following types of materials are usually the most ductile

A Face centered cubic lattice
B Body centered cubic lattice
C Hexagonal close packed lattice
D All of the above

Correct Answer: Face centered cubic lattice

A face-centered cubic crystal structure will exhibit more ductility (deform more readily under load before breaking) than a body-centered cubic structure.
The bcc lattice, although cubic, is not closely packed and forms strong metals. Alpha-iron and tungsten have the bcc form.
