the answer would be b because b is the only one that changes while a and c does not change for their type.

Explanation:
Proteins and nucleic acids play important biological functions : they catalyze and regulate reactions, transport substrates, code and transcribe genetic information. It is widely appreciated that water molecules play an invaluable role in governing the structure, stability, dynamic, and function of these biomolecules
Water, without any doubt, must be considered an integral part of biological macromolecules. The living world should be thought of as an equal partnership between proteins, nucleic acids and water
