Explanation / Answer

Answer 2. All of these.

We have 4 biomolecules in our body namely, carbohydrates, lipids, Nucleic acids and the proteins. These options relate to the synthesis of these biomolecules in our body, they are spontaneous in our body.

Answer 3. It is an ester bond

In the ester bond formation, 2 molecules are joined together by the condensation reaction, means a water molecule is taken out and the two molecules are joined together.
