The sharp melting point of crystalline solids is due to

A. a regular arrangement of constituent particles observed over a short distance in crystal lattice.

B. a regular arrangement of constituent particles observed over a long distance in crystal lattice.

C. Same arrangement of constituent particles in different directions.

D. different arrangement of constituent particles in different directions.

Answer:

B. a regular arrangement of constituent particles observed over a long distance in crystal lattice.

Explanation:

Because all of the component atoms, molecules, or ions are the same distance from the same number and type of neighbors, crystals have relatively sharp, well-defined melting points; that is, the regularity of the crystalline lattice provides similar local environments.
