Which statement describes the properties of LDPE?

Explanation:
LDPE’s behavior under stress comes from its molecular structure: many side chains cause a less ordered, more amorphous arrangement. This reduces stiffness and crystal packing, so the chains can slide past each other when loaded. The result is a material that can bend, absorb impact, and resist cracking—so it’s tough and flexible. The other descriptions imply stiffness, brittleness, or overly rigid behavior, which doesn’t match LDPE’s characteristics.
