C Correct answer
Explanation

Sonorosity is the property of producing a ringing sound when struck - this is a characteristic property of metals, which is why bells are made of metal. Non-metals are typically non-sonorous - they don't produce ringing sounds. The question asks which is NOT a property of non-metals, so sonorous is the correct answer because it's a metal property, not a non-metal property. Non-lustrous (dull appearance), transparent (allowing light through), and non-ductile (cannot be drawn into wires) are all properties that can describe non-metals.
