During the rarefaction phase of the crystal, density is?

Explanation:
In a longitudinal wave traveling through a crystal, the rarefaction phase is where particles are pulled apart, increasing the distance between them. Since density is mass per unit volume, when the same amount of mass spreads over a larger volume, the density decreases. So, during rarefaction, density is low. This contrasts with compression, where particles are pushed closer together and density is high. Therefore, the correct description is low density.
