Question

which of these is malleable?
marble
stone
air
wax

Explanation:

Malleability is the ability to be shaped or deformed by pressure (like being rolled into sheets) without breaking. Marble and stone are hard, brittle solids and not malleable. Air is a gas and doesn't have a fixed shape to be malleable in the typical sense. Wax is a soft solid that can be easily shaped (e.g., molded) when pressure is applied, so it is malleable.

D. wax
