Answer:
Option (1).
Step-by-step explanation:
Saturated fatty acid may be defined as the fatty acid with the single bonds between the carbon atoms. The unsaturated fatty acid consist of double and triple bond in its structure.
The melting points differs between the saturated and unsaturated fatty acid. The saturated and unsaturated fatty acids have high difference in their melting point and this difference may changes as the double and triple bonds are increased or decreased in the fatty acid structure.
Thus, the correct answer is option (1).
