The correct answer is option D that is only coding exons are spliced together to make finished mRNA because exons are the region of mrna that are coding, introns are non coding region and they are spliced out during splicing reaction.

So, option A is wrong.

Option B and C are wrong because adding cap and poly A tail are different reactions of RNA processing and they are not part of RNA splicing..
