Nucleic acids are synthesized from monomers that are activated by linking them to a carrier molecule in an energy-requiring reaction.
a. Nucleic acids are synthesized from monomers that contain a high-energy disulfide bond and they are already activated and do not require a carrier molecule.
b. Nucleic acids are synthesized from monomers that contain a high-energy phosphodiester bond and they are already activated and do not require a carrier molecule.
c. Nucleic acids are synthesized from monomers that contain a low-energy disulfide bond and they are already activated and do not require a carrier molecule.
d. Nucleic acids are synthesized from monomers that contain a low-energy phosphodiester bond and they are already activated and do not require a carrier molecule.

The given statement is a false statement as nucleic acids are synthesized by the polymerization process. In which linking the various nucleotides or deoxynucleosides with three phosphate groups or dNTPs (deoxynucleotide phosphate) attached to each other by a high energy phosphodiester bond takes place. These are already activated and does not require any carrier molecule to be liked with.

Thus, the correct answer is - option B.
