Which sample demonstrates particles arranged in a regular geometric pattern?

A. CO2(g)

B. CO2(s)

C. CO2(l)

D. CO2(aq)

E. None of the above

I chose E because I thought that covalent molecules, when solid, would be arranged in a random pattern, especially since this is a non-polar molecule. But apparently they will be arranged in a regular geometric pattern because the answer is B. So could someone confirm the answer and also tell me when solids have regular geometric pattern? Are there any rules?
