Solid: Properties, Classification, Types, Examples
Properties of solid. 1. They have fixed shape size and volume. 2. They are incompressible and inflexible. 3. The particles constituting a solid may be atoms (e.g, in metal), ions (e.g, in NaCl), or molecules (e.r, dry ice). These occupy a fixed position and only oscillate about their mean position. 4. Molecules have a short intermolecular distance.

Brittleness is a property of solid which:
And the solid does not return to its original shape and it's not due to its brittleness property. Hence, the option (B) is incorrect. The solid regains to its original state not due to the property of brittleness. Hence, option (C) is incorrect. If the material can break into small pieces, that type of property is known as brittleness.
