A) The lower the degree of unsaturation, the lower is the melting point.

The greater the degree of unsaturation (more double bonds) in a fatty acid, the lower its melting point. This is because unsaturated fats, with their kinked structures due to double bonds, do not pack together as tightly as saturated fats, making them easier to melt.
