The picture below shows the particles in one section of an unknown pure substance.

The sample shows two close-up views of particles. The left close-up shows seven compound molecules that are uniformly spaced. The right close-up view shows a question mark.

Which option represents the particles in another section of this pure substance?

Since the left close-up shows compound molecules that are uniformly spaced, it is likely that the particles in another section of this pure substance would also consist of compound molecules that are uniformly spaced.
