D Correct answer
Explanation

A cistron is the functional unit of a gene that codes for a single polypeptide chain. A replicon is a DNA unit capable of replication, a muton is the smallest mutable unit, and a codon is a triplet coding for one amino acid. Cistron aligns with the 'one gene-one polypeptide' concept.
