Al is more ductile than others.

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

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.

Because it has less than 0.15% carbon.

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.

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.

I think, Aluminium is more ductile than mild steel.

Mild steel having more ductile behavioural phenomenal than the aluminium and reason is that;
Mild steel shows BCC crystal structure and Aluminium shows FCC.
And BCC is more ductile than FCC structure and one more best reason for why aluminium shows a less ductile than mild steel is. FCC crystal structure cannot show ductile to the Brittle transition temperature and only BCC can shows.
This is the main reason.

Copper is more ductile than Mild steel.

The ductility of steel varies depending on the alloying constituents. Increasing levels of carbon decreased ductility.
The most ductile metal is platinum and the most malleable metal is gold.
