Question

State in which atoms or molecules are very close together and are regularly arranged

Answer 1

Solid, because the atoms maintain their form and do not take the shape of their container. The particles share tight, close bonds due to this set shape

Answer 2

The state in which atoms or molecules are closely packed together to the point where they are regularly arranged would be a solid.

The reason for this is because solids have a fixed shape, which explains why their molecules are regularly arranged and packed together unlike liquids and gases which have molecules that have more room to roam and are less packed.
