Model Answer
(B) They can be beaten into thin sheets.
Metals possess the property of malleability — they can be beaten into thin sheets. Gold and silver are the most malleable metals. Metals are also good conductors of heat and electricity, and form basic (not acidic) oxides.

Explanation
- The question asks for a physical property of metals.
- Option B describes malleability, which is a key physical property of metals confirmed in Activity 3.3.
- Option A is wrong — metals form basic oxides (non-metals form acidic oxides).
- Option C is wrong — metals are good conductors.
- Option D describes non-metals (brittle, dull).
- Remember: malleability and ductility are the two most commonly tested physical properties of metals in MCQs.
