assertion.

3) Assertion is true but reason is false.

4) Assertion and reason both are false​

Answer - Correct option with respect to metals is - 3) Assertion is true but reason is false

Metals are sonorous which means metals produce ringing sound on being hit. This happens due to high delocalisation of electrons in metals.

Brittle elements are the ones which break easily on being hit by force. Metals are not brittle in nature.

They are rather malleable that is they can be shaped easily.
