F)only answers a and b are correct

Quizplus · Accepted Answer

The melting point of a fat is dependent on all of the factors listed in choices (A), (B), (C), and (D). The degree of saturation affects the melting point because unsaturated fatty acids are usually liquid at room temperature, while saturated fatty acids are usually solid. The length of the fatty acid affects the melting point because longer fatty acid chains have more van der Waals forces holding them together, making them solid at higher temperatures. The cis-trans configuration affects the melting point because trans fats have straighter chains that can pack more tightly together, making them more solid at room temperature. Finally, the crystalline structure affects the melting point because different crystal forms of the same fat can have different melting points. Therefore, all of the above answers are correct.
