Answer: Solid
Explanation: a solid has its own shape and volume due to strong intermolecular (IM) attraction making it rigid.
a liquid has a volume but no shape due to relatively weak IM force, making it take the shape of the container it's in.
gases have no shape or volume due to even weaker IM force.
plasma can be considered a gas but it has charged particles and ions. so the answer is Solid due to strong IM force.
