None of the above

Explanation:
Detailed explanation-1: -So, the correct option is ‘Intron’.
Detailed explanation-2: -One of the steps in this processing, called RNA splicing, involves the removal or “splicing out” of certain sequences referred to as intervening sequences, or introns. The final mRNA thus consists of the remaining sequences, called exons, which are connected to one another through the splicing process.
Detailed explanation-3: -RNA splicing is a process that removes the intervening, non-coding sequences of genes (introns) from pre-mRNA and joins the protein-coding sequences (exons) together in order to enable translation of mRNA into a protein.
