Which one of the following is ductile?
Correct answer: D. All of these
- A. Aluminium
- B. Copper
- C. Gold
- D. All of these
Explanation
The correct answer is Option D: All of these. Ductility is a physical property of materials that relates to their ability to be stretched into wires without breaking. Aluminium, Copper, and Gold are all known for their ductility. Aluminium is widely used in industries due to its combination of ductility and light weight. Copper is highly valued for its electrical conductivity and ductility, making it ideal for electrical wiring. Gold, although expensive, is extremely ductile and can be drawn into very fine wires. Therefore, since each of these metals is ductile, the correct choice is 'All of these'.
