The correct answer is introns.

Introns are non-coding sequences in the immature mRNA made from DNA transcription. Since they are non-coding, they do not contribute to the final protein that will be translated; therefore introns need to be removed. Introns are removed by RNA splicing; and this is succeeded by 5' capping and adding of poly-A tail.
