Question

Which of the following metals has more ductility?

• A. Zinc
• B. Tin
• C. Aluminum
• D. Copper

Hint:

The extensive use of a metal in wiring (like copper and aluminum) is a strong indicator of its high ductility.

Answer 1

The Correct Option is D

Step 1: Define ductility. Ductility is a mechanical property of a material that describes its ability to be stretched, pulled, or drawn into a thin wire without breaking.
Step 2: Compare the ductility of the given metals. While all are metals, their ductility varies. Copper is exceptionally ductile, which is why it is the standard material for electrical wiring. Aluminum is also very ductile. Zinc and tin are comparatively brittle and have much lower ductility. Between aluminum and copper, copper is generally considered to have superior ductility.
