Which statement best describes a difference between saturated fats and unsaturated fats?

Unsaturated fats contain at least one carbon-carbon double bond. The double bond can create a bend in the fatty acid chain, so the molecules do not pack together as tightly as the straighter chains of saturated fats. Less tight packing generally means a lower melting point, making “lower melting points because of a double bond that causes the molecule to bend” the best description.
