Solution

The correct option is A DNA
DNA is capable of self replication. Enzyme helicase unwinds the DNA strand and replication fork is formed. Enzyme DNA polymerase copies each strand using the base-pairing rule. RNAs are not capable of self replication except ribozymes. Proteins and enzymes cannot self replicate. These are translated from mRNA.
Thus, the correct answer is option A.
