Solution

The correct option is C Assertion is correct, but Reason is incorrect.
Meaning of sonorous:
1. capable of giving a deep, resonant sound
2. makes a ringing sound when hit
Electron bonding in metals is highly delocalized (due to very low electronegativity). This means that when hit, the electron cloud moves extremely easily - there is very little energy dissipated. This allows the incoming kinetic energy to be easily propagated as a form of disequilibrium (wave). The basic requirement for a metal to be sonorous it should exist as a sheet and have to be of relatively low density.
Metals are strong and dense lattice structure that imparts its high strength.
This assertion is correct but the reason is wrong.
Option C is correct.
