I think, Aluminium is more ductile than mild steel.

Ductility of metals depends on the strength of metallic bonding among atoms.
(attraction between sea electrons/that depend on the number of valence electrons and atomic kernels).
So the answer is Al.

So the answer is Al.

Given materials are Ms, Al, Cu, and Ni. There didn't mention any condition like whether it is proportional limit, elastic deformation zone, plastic deformation zone or ultimate zone.
Then according to material properties are valid under the proportional limit.
So maximum value of young's modulus its gives high ductility.
E (steel) =200Gpa.
E (copper) =117 Gpa.
E (Al) = 69 Gpa.
E (Nickel) =170 Gpa.

Because it has less than 0.15% carbon.

Mild steel is more ductile metal because undergo large permanent strain before failure. And large reduction in area before fracture.
If strain post elastic strain is greater than 5%, it is called ductile material. Also mild steel is more elastic than rubber.

Ductility depends upon the elongation of material, when applied the tensile stress.

Less carbon content. Carbon contains hardness.

Material Ductility, % reduction in area.
Mild steel 52.
Aluminium alloys 35-39.
