Answer 1

Option	Response	Reason
A	Wrong	Fatty acids are strongly hydroPHOBIC. It can be seen in the cell membrane itself where the lipids are arranged as bilayers and the fatty acids tails are pointing towards each other to protect themselves from water
B	Wrong	Phosphatidic acid is a very rare fatty acid constituting less than 0.2% of cell membrane lipids.
C	Wrong	Fatty acids are of two types:- saturated and unsaturated. Saturated fatty acids don't have any double or triple bond. Unsaturated fatty acids contain one or more than one double or triple bond.
D	Wrong	Fatty acids are not constituents of sterols. For example, cholesterol is made up of cyclopentanoperhydrophenanthrene Nucleus.
E	Right	Arachidonic acid (a fatty acid) is the precursor of Prostaglandins.
