Question

which box best represents the particles in a solid?

Explanation:

In a solid, particles are closely packed together in an orderly arrangement. Box B shows particles closely packed and arranged in an orderly manner, which is characteristic of a solid. Box A likely represents a liquid (particles are close but can move more freely than in a solid). Box C likely represents a gas (particles are far apart). Box D may represent a different state or a less - ordered structure.

Answer:

B.
