A liquid can easily change its shape but a solid can not because(a) the density of a liquid is smaller than that of a solid(b) the forces between the molecules is stronger in solid than in liquids(c) the atoms combine to form bigger molecules in a solid(d) the average separation between the molecules is larger in solids.

Answer»

(b) the forces between the molecules is stronger in solid than in liquids

EXPLANATION:  

The shape will change only if the molecules have some freedom of movement. In a solid the forces between the molecules are so strong that they cannot move easily, thus the shape is not changed.
