The answer is A) it is stored only in the nucleus of all living cells
The genetic code is the set of rules that explains how the information is transferred from DNA to the proteins. It is made of the same components in all living organisms and is found in the base sequence of the nucleic acids. Also, it is read only in groups of three nitrogenous bases. But it is not stored only in the nucleus of the cells. DNA material is present in mitochondria as well. Nevertheless, in Prokaryotes, there is no nucleus, so the genetic information is in the cytoplasm.
