Detailed explanation-1: -Graphite is a non metal as it shoes all the above properties except conduction. So it is clear that graphite is not malleable hence, the correct option is B.
Detailed explanation-2: -Answer: The only non metal which is malleable is graphite. Graphite is a large covalent structure in which each carbon atom is covalently linked to three other carbon atoms.
Detailed explanation-3: -Definition of Malleability Malleability is the physical property of a solid to bend or be hammered into another shape without breaking. If malleable, a material may be flattened into a thin sheet by hammering or rolling. Examples of malleable metals are gold, silver, aluminium, copper etc.
Detailed explanation-4: -Zinc is an exception among metals that does not shows malleability.
Detailed explanation-5: -Malleability is a property of a material by which it can be beaten to form thin sheets. Most metals are malleable. Examples of malleable metals are zinc, iron, aluminum, copper, gold, and silver.
