Explanation / Answer

The answer is TRUE.

London Forces is associated with different electron environment. In saturated fatty acid the electron environment is uniformed and will be stronger than the cis-oleic acid where the elctron environ will be distorted due to the presence of the pi-bond.

The structure of Cis-Oleic acid is almost symmetric with respect to the double bond and packing of the molecules will be tighter than the saturated fatty acid (tend to form coil like structure), so the melting point will be higher.
