The correct answer will be- Deoxyribose nucleic acid or DNA

DNA is the nucleic acid which acts as the genetic material of all the organisms on Earth except a few viruses where RNA is the genetic material.
The DNA is the genetic and heredity material of the organisms as the DNA stores the information of the organism in a coded form which is passed from parents to offspring through reproductive mechanisms.
The structure of DNA contains a five-carbon sugar, a phosphate group and the nitrogenous bases. it is the sequence of these nitrogenous bases which contain the code of life in DNA.
Thus, DNA is the correct answer.
