The statement that compression of crystal leads to high particle density indicates:

Explanation:
Density equals mass per unit volume. When you compress a crystal, its volume becomes smaller while the total mass stays the same, so the density increases. This higher density means more particles are packed into each unit volume, i.e., higher particle density. The other options don’t fit because compression doesn’t add mass, so density wouldn’t decrease or stay the same, and compression alone doesn’t cause melting, which requires a phase change with energy input.
