Which of these statements is not true? a) amino acids, nucleic acids, and carbohydrates are found in all living organisms. b) amino acids, nucleic acids, and carbohydrates all link as only linear molecules. c) amino acids, nucleic acids, and carbohydrates can all form complex macromolecules. d) amino acids, nucleic acids, and carbohydrates all polymerize via condensation reactions.

The correct answer will be option-B

Explanation:

Three types of molecules are found in all the organisms which are the amino acids, carbohydrates, nucleic acids.

The amino acid is the monomer of the protein whereas nucleic acid and carbohydrates are the class of molecules which further form complex molecules by a condensation reaction or dehydration reaction.

Since these molecules do not link with each other in their linear form only, therefore, Option-B is the correct answer.

Thus, Option-B is the answer.

the answer would be..

b. sucking
