Solution

The correct option is A Trihydroxy propane
Lecithin is also known as phosphatidylcholine (a group of phospholipids) which are important for maintaining the cell structure and metabolism.
Lecithins are composed of phosphoric acid, choline, esters of glycerol and two fatty acids.
Thus, during the breakdown of lecithin fatty acid, choline and sphingosine are obtained.
So the correct answer is 'Trihydroxy propane'.
