What is sonority?

Iron, aluminium, copper, and other materials are all acquainted to metal. The physical and chemical characteristics of certain metals allow them to be separated from non-metals. Metals have qualities including hardness, lustre, malleability, ductility, sonority, and conductivity.

Let's talk about the characteristics of metals.
The feature of a metal that allows it to be pounded into thin sheets is known as malleability. Metals that can be pulled into sheets when hammered exhibit this feature. Example: Fe nails with Al wire

Ductility is the ability of a metal to be pulled into thin wires.
When something constructed of metal is struck firmly, it has the quality of producing a ringing sound. The metals made what was described as thunderous ringing noises. Sonority is the name given to this characteristic of a metal.
When a metal surface is exposed to a dry or moist environment, corrosion of metal, also known as metal surface deterioration, begins at the metal surface. For instance, iron rusting.
Sonority, then, is the ability of a metal to produce a rich or ringing sound.

Hence, the correct answer is option A.
