Answer 2

Answer:

The correct answer is lipids.

Lipids refer to the group of organic fatty compounds such as oils, wax, fats, sterols etc which are not soluble in plar solvents such as water. They are soluble in non-polar solvents such as ether.

In contrast to carbohydrates, proteins, and nucleic acids, lipids are not the polymers of same repeating unit. They can be of various types such as fatty acid chains, glycerolipids, phospholipid, spingolipids etc.

Carbohydrates are polysaccharides, proteins are polypeptides, and nucleic acids are polynucleotides in nature.
