• E. $a-4,b-3,c-2,d-1$

Answer 1

The correct option is A $a-4,b-3,c-1,d-2$

A triglyceride is an ester made of glycerol and three fatty acids. Neutral fat or fat stored in the body is nothing but triglycerides.Phospholipids are the lipids which has phosphorous attached to the lipids molecules. It is an important constituent of cell membrane. It is made up of two hydrophobic fatty acid tails and a hydrophilic head consisting of a phosphate group. Steroids are the organic molecules which play an important role in the growth and development of the body. The sex hormones in animals are steroids. Wax is an ester of fatty acid and long-chain alcohol. It is also used in commercial production of lubricants, rust-preventive coatings, shoe polish. It is present on the feathers to prevent the water loss and it is also present on leaves to curtail transpiration.

So, the correct answer is option A.
