RNA transcripts become functional after synthesis, unlike In Eukaryotic cells where we have pre-mRNA that has to undergo splicing to remove all the introns. In some genes, not all the DNA sequence is used to make proteins. Introns are non-coding sections of RNA transcript, that are spliced out before the RNA molecule is translated into a protein. Primary transcripts contain both exons and introns, introns are the noncoding part.

Option 2 is the correct answer.
