Which low-energy state of condensed matter is characterized by structural rigidity and resistance to changes of shape or volume? gas liquid plasma solid

Solid is the answer. 

When matter is in its solid state, its molecules are more rigid and move less. they are also more resistant to changes in shape. Think of water in its solid form, ice. Ice is much harder to change the shape of than liquid water, and is much more rigid in its structure. 

the answer is true.

this statement is true.
