Solution:
Concept- Materials that can make sound are said to be sonorous. A sonorous sound is one that has a deep, rich quality. Bells, for instance, are fashioned of a sonorous bronze alloy of copper and tin. Steel also makes a sonorous sound when struck with a spoon. Elasticity is what gives metals their sonorous quality.We are aware that metals are naturally electropositive. The electron cloud that is present in metals can quickly move when they are struck. Because of how little energy the passage of electrons produces, kinetic energy may be easily transmitted as sound waves. Metals' flexibility is the name for this characteristic.
The sonorous property of metal is due to its elasticity. Elasticity makes the metal produce sound and we can use them for producing sounds. Since mercury cannot be struck because it is a liquid metal at normal temperature, there will be no sound. Platinum and gold are inert metals. Typically, they don't make a sonorous sound. When struck, they only make a very small sound. Out of all the possibilities presented, silver has the most flexibility. Silver is the most sonorous metal as a result.
Hence, the correct answer is option 4.
