In eukaryotes, the coding sequences or expressed sequences are defined as exons. Exons appear in mature or processed RNA. The exons are interrupted by introns, they do not appear in mature or processed RNA.

The correct answer is option 'C': (i) exons, (ii) introns.
Explaination:
In eukaryotes, the structural genes are composed of coding and non-coding sequences. These sequences play important roles in gene expression and protein synthesis. The coding sequences are responsible for the production of functional proteins, while the non-coding sequences do not code for proteins but have other regulatory functions.
(i) Exons:
- Exons are the coding sequences of DNA or RNA that are transcribed into mRNA and eventually translated into proteins.
- They contain the information necessary for the synthesis of functional proteins.
- Exons are usually uninterrupted and directly translated into amino acids during protein synthesis.
(ii) Introns:
- Introns are non-coding sequences of DNA or RNA that are transcribed into pre-mRNA but are removed during the process of RNA splicing.
- They are interspersed between exons and do not code for proteins.
- Introns have regulatory functions and play a role in gene expression and alternative splicing.
- Alternative splicing allows for the generation of multiple protein isoforms from a single gene by selectively including or excluding certain exons during mRNA processing.
The presence of introns in eukaryotic genes provides an additional level of gene regulation and allows for the generation of diverse protein isoforms. The process of RNA splicing removes the introns and joins together the remaining exons to form the mature mRNA molecule, which can then be translated into a functional protein.
Therefore, the structural genes in eukaryotes possess coding sequences known as exons and non-coding sequences known as introns. Option C, (i) exons, (ii) introns, is the correct answer.
