Because mild steel having less carbon than other materials.

No, Al is most ductile among all.

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.
The most ductile metal is platinum and the most malleable metal is gold.

Copper 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.

I think, Aluminium is more ductile than mild steel.

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.

I think copper is more ductile material.

Copper has about 60% more ductility than Aluminium.

Ductility: gold > silver > iron > copper > aluminum > zinc > tin > lead.
