Carbon content is responsible for more Ductlility?

Mild steel has maximum ductility. Those materials show the lower amount of the carbon. Alloying elements from one metal to another metal.

I think copper is the right answer.

I think Aluminum is the right answer.

The correct answer is Copper.

Copper is known for its high ductility, with a ductility percentage of around 50-60%. This means that copper can be stretched or drawn out to a significant extent without breaking.

Here's a rough ranking of the materials you listed by their ductility:

1. Copper (50-60%)
2. Aluminium (20-30%)
3. Mild steel (15-25%)
4. Nickel (10-20%)

Note that ductility can vary depending on the specific alloy, processing history, and testing conditions.

However, in general, copper is considered one of the most ductile metals.

Mild steel has moderate ductility, while nickel has relatively low ductility compared to the other options. Aluminium has intermediate ductility, but it's still lower than copper.

Copper has maximum ductility.

Gold has maximum reliability.

Nickel > Copper > Aluminum > Mild Steel.

So, Nickel has the maximum ductility among the given options.

So, I think option C is the correct answer.
