Hi here is the solution for your question. I hope I could help you in future also.if anything is not clear to you please let me know before giving your valuable feedback.
I would like to improve that in the future
Thanks
Solution
I think It should be option d
Unsaturated fatty acids having lower melting point than that of saturated fatty acids because of the cis arrangement of double bonds present in the unsaturated fatty acids which resulted in a bend in structure that responsible for irregular shape. Which decreases the intermolecular vandarwall force of attraction between the molecules ultimately results in the decrease in the melting point.
Example of unsaturated fatty acid is vegetable oil
Example of saturated fatty acid is butter.
I hope it will help you. If I missed anything please let me know before giving your rating.

Why do saturated fats have higher melting points than unsaturated fats? Saturated fats stack better than unsaturated fats and therefore have more dispersion forces between them. Saturated fats stack better than unsaturated fats and therefore have fewer dispersion forces between them. Unsaturated fats stack better than saturated fats and therefore have more dispersion forces between them. Unsaturated fats stack better than saturated fats and therefore have fewer dispersion forces between them.

Which of the statements are true? Fats that contain more unsaturated fatty acid residues than saturated fatty acid residues are more likely to be liquid at room temperature. Tracleucerols (triglycerides) always contain three identical fatty acids. Unsaturated fats have higher melting points than saturated fats. Triacylglycerols (triglycerides) are composed of fatty acid residues and glycerol. Unsaturated fats are more likely than saturated fats to be liquid at room temperature.
