• A. Non metals are malleable and ductile
• B. Non metals are brittle
• C. Non-metals are usually liquids
• D. Non-metal can produce clanking noise

Answer 1

The correct option is B

Non metals are brittle

Non - metals are brittle in nature, they break into pieces when hammered, so they do not produce clanking noise when hammered (not sonorous). Diamond is an exception, it is the hardest known material. Non-metals are usually solids or gases.
