Exon: The coding sequences or expressed sequences are defined as exon. Exons are said to be those sequences that appear in mature or processed RNA.

The Coding Segment of DNA
The coding segment of DNA refers to the sequence of nucleotides that encode the information for the synthesis of proteins. Proteins are necessary for the structure, function, and regulation of the body's tissues and organs.
Codon
A codon is a sequence of three nucleotides on the DNA molecule that codes for a specific amino acid during protein synthesis. There are 64 different codons that can be formed by the combination of the four nucleotides (adenine, guanine, cytosine, and thymine) in DNA. The sequence of codons determines the sequence of amino acids in the protein, and therefore its structure and function.
Intron
Introns are non-coding segments of DNA that do not code for proteins. They are interspersed between the coding segments, or exons, and are removed during RNA processing before the final mRNA is formed.
Muton and Replicon
Muton refers to the smallest unit of DNA that can undergo a mutation, while replicon refers to a DNA segment that can replicate independently. These terms are not directly related to the coding segment of DNA.
Conclusion
Therefore, the correct answer to the question is option D, Codon, as it refers specifically to the sequence of nucleotides that code for amino acids during protein synthesis.
