Correct Answer: DNA

Solution : The correct option is DNA.

DNA (Deoxyribonucleic Acid) is principally responsible for the transmission of genetic information from one generation to the next. DNA is made up of a particular sequence of four nucleotide bases that encode the instructions required for living creatures to develop, operate, and reproduce. DNA replication occurs during reproduction, guaranteeing that each new generation acquires a complete set of genetic information. Specialised reproductive cells carry a unique combination of genetic material from both parents and merge during fertilisation to produce children with a variety of characteristics. DNA also contributes to genetic variety through mutations, which aids in species adaption and evolution.
