Final Answer :
D
Explanation :
DNA is the only known molecule that can replicate or reproduce itself, with the help of enzymes and other proteins. RNA can be replicated by DNA in a process called transcription, but RNA cannot replicate itself. Monoamine oxidase is an enzyme that breaks down neurotransmitters in the brain and is not involved in replication. Messenger RNA is involved in the process of transcription, but it cannot replicate itself.
