Solution

The correct option is A Statement A is correct and B is wrong.
Heterogenous nuclear RNA is the original product of transcription of eukaryotic genes which is much larger than the mature mRNA due to the presence of noncoding regions which are then removed during post-transcriptional modification. The protein coding part of the gene is exon while the gene sequences that are present between exons and do not code for any protein product are called introns. Hence RNAsplicing removes introns. The reason is incorrect. Thus, the correct answer is option A.
